We made the discovery by applying a magnetic field and looking for undulations in sample properties such as the resistance
when we placed a small sample of the insulating material on a cantilever in a magnetic field,
But then they came up with the idea of a rotating magnetic field. very time the field flips,
when it's exposed to a magnetic field. Known as giant magnetoresistance, this property is crucial to achieving the large storage capacity we've come to enjoy in our hard drives,
When materials with giant magnetoresistance are exposed to a magnetic field, they significantly alter their electronic resistance.
The material has such incredible magnetoresistance because of another interesting property-its electrons are superfast, with a top speed of around 300 km/s. In a magnetic field,
which causes an increasing percentage of electrons to flow in the'wrong'direction as the magnetic field becomes stronger."
"The faster the electrons in the material move, the greater the Lorentz force and thus the effect of a magnetic field,"explains Binghai Yan, one of the lead researchers from the Max Planck Institute for Chemical Physics of Solids
After writing a quantum state onto the nuclear spin of the europium using laser light the team subjected the crystal to a combination of a fixed and oscillating magnetic fields to preserve the fragile quantum information.
This method uses magnetic fields to break the time-reversal symmetry with certain specialized garnet and ferrite materials.
Magnetic fields are also sources of interference in many applications such as cold atom microsystems. These constraints have deterred availability of Faraday effect isolators for on-chip optical systems till date.
and enables the manipulation of nanomagnets with spin currents rather than magnetic fields, "explained Gyung-Min Choi,
Eventually, Prakash decided to build a rotating magnetic field that could act as clock to synchronize all the droplets.
Prakash realized that a rotating magnetic field might do the trick. Katsikis and Prakash built arrays of tiny iron bars on glass slides that look something like a Pac-Man maze.
Next, they turned on the magnetic field. Every time the field flips, the polarity of the bars reverses, drawing the magnetized droplets in a new, predetermined direction, like slot cars on a track.
Combined with the fact that the magnetic field can control millions of droplets simultaneously this makes the system exceptionally scalable."
Coupled with the unique properties of hard x-rays, namely penetration of complex environments and operation in electric and magnetic fields, such optics will enable highest-resolution imaging of systems under in-situ and in-operando conditions,
when the material is exposed to a magnetic field. This giant magnetoresistance, which is responsible for the large storage capacity of modern hard discs,
Modern hard discs utilize this phenomenon to significantly alter the resistance of a material by exposing it to a magnetic field.
The resistance of niobium phosphide changes so dramatically in a magnetic field, because the charge carriers are deflected by a phenomenon known as the Lorentz force.
This force causes an increasing percentage of electrons to start flowing in the"wrong"direction as the magnetic field is ramped up,
the greater the Lorentz force and thus the effect of a magnetic field,"explains Binghai Yan, a researcher at the Max Planck Institute for Chemical Physics of Solids in Dresden.
For their investigations, the scientists used the Dresden High Magnetic field Laboratory, as well as the High-Field magnet Laboratory at Radboud University in Nijmegen, Netherlands,
size, and structure to facilitate desired interactions with light, electrical or magnetic fields, or chemical environment to provide unique functionality in a wide range of applications from energy to medicine.
temperature, chemicals, electric field or magnetic field. These various stimuli can be used to make the materials change colour,
which a magnetic field induces a Lorentz force on moving electric charge carriers, leading to deflection and a measurable Hall voltage.
Arraythe research team used the Dipole Coil Resonance System (DCRS) to induce magnetic fields, which was developed by the team in 2014 for inductive power transfer over an extended distance.
in order to generate rotating magnetic fields, which was embedded in the Tx's flat platform. This has made it possible for mobile devices to receive power from any direction.
In addition, the DCRS works at a low magnetic field environment. Based on the magnetic flux shielding technology developed by the research team,
Other approaches involve using magnetic fields to control the plasma sheath or injecting water or other liquids into the plasma sheath to make it more permeable to radio signals,
The devicesperformance was characterized in part using optical microscopy in a magnetic field at the CFN, performed by CFN staff scientist Mircea Cotlet, Luozhou Li,
multi-rotor UAV (Unmanned aerial vehicle) that uses its own structural elements to store fuel. e realized that the structures of these drones were hollow inside,
The lightweight lithium-polymer hybrid fuel cell that converts the hydrogen gas into electricity to power the rotors was developed by a sister company,
When the researchers applied a magnetic field, they observed breaking of the electron pairs one at a time. A theory of electron pairing without formation of a superconducting state was published first by David M. Eagles in 1969.
These images show differential conductance through the quantum dot as a function of the gate voltage that controls the number of electrons in the dot (x-axis) and the applied magnetic field (y-axis).
These new phenomena rely on the transport of thermal energy, in contrast to the conventional application of magnetic fields, providing a new,
and enables the manipulation of nanomagnets with spin currents rather than magnetic fields, explained Gyung-Min Choi,
Its motions are controlled by external magnetic fields. he entire walking motion is embedded into the mechanics of the robot body
the proper application of a magnetic field to the permanent magnet on its back causes its body to flex.
Then, another sequence of magnetic fields causes the robot body to twist slightly which breaks the front feet adhesion,
If you wrapped one up into a sphere, its magnetic fields would point away in all different directionso they stay in neat little packages
ith adducted rotors you immediately not only protect people and property if you were to bump into them,

ESR works by combining a magnetic field with microwave energy, which together, get molecular bonds vibrating in telltale ways.
They generate no magnetic field, produce no magnons, and there appears to be no way for the spins to communicate with one another.
this technique could be important in the development of devices that are highly sensitive to magnetic fields,
Furthermore, the magnetisation could only be determined indirectly through the resulting distribution of the magnetic field. ur process enables you to map the magnetisation in directly in 3d.
Knowledge of the magnetisation is prerequisite for improving the sensitivity of magnetic field detectors, said Kronast.
such as those developing more sensitive devices for medical imaging as procedures-including magnetoencephalography-depend on externally detecting very weak magnetic fields created by the electrical activity of individual nerve cells. l
