and cost associated with using magnets and magnetic materials. Freed from a reliance on magnetic effects the new circulator has a much smaller footprint
The researchers device works by mimicking the way magnetic materials break the symmetry in wave transmission between two points in space a critical function that allows magnetic circulators to selectively route radio waves.
Injecting magnetic materials known as contrast agents can help boost the visibility of certain tissues but these agents are designed typically to break down soon after the MRI is performed.
They found that graphene's Hall voltage-a voltage in the perpendicular direction to the current flow-depended linearly on the magnetization of yttrium iron garnet (a phenomenon known as the anomalous Hall effect seen in magnetic materials like iron and cobalt.
called a solenoid, outside near the tumor. Electricity passed through the solenoid creates a weak radiofrequency field.
The field causes the magnetic tails of the chain to vibrate bursting the liposome spheres,
the chemical process in this case controls magnetism in carefully chosen strongly ferromagnetic material systems. The working principle used in this case is similar to the concept of lithium-ion batteries.
A spin wave is caused by a perturbation of the local magnetisation direction in a magnetic material.
and magnetic materials interact with each other due to their opposite magnetic ordering direction of magnetization: in magnetic layers storages the magnetic field tends to arrange spins in one direction,
"made of nanolayers of ferromagnetic material, superconductor and other metals. By changing the direction of magnetization it is possible to control the current in superconductor.
Stable whirls in magnetic materials (see figure) were predicted over 25 years ago, but the experimental realization was achieved only recently.
Conventional methods typically employ static-field elements such as solenoids, which are coils of wire that create uniform magnetic fields, to focus the electron beams.
#Scientists create cheaper magnetic material for cars, wind turbines Karl A. Gschneidner and fellow scientists at the U s. Department of energy's Ames Laboratory have created a new magnetic alloy that is an alternative to traditional rare-earth permanent magnets.
and Mahmud Khan (now at Miami University) demonstrated that the cerium-containing alloy's intrinsic coercivity--the ability of a magnetic material to resist demagnetization--far exceeds that of dysprosium-containing magnets at high temperatures.

"In our study, we make use of the fact that a heat current passing through a magnetic material creates a separation of electron spins.

When the scientists applied an electric current to the metal layers the stripes stretched through the channel
and as heat-resistant and magnetic materials. The embedded metal ions in the Ni1-xcuxcr2o4 spinel system cause a distortion of the crystal structure.
In the 1840s, physicist James Prescott Joule discovered that iron-based magnetic materials changed their shape but not their volume when placed in a magnetic field.
#Magnetic material unnecessary to create spin current (Nanowerk News) It doesn't happen often that a young scientist makes a significant and unexpected discovery,
