NMR and MRI measurements on the nanoscale have been done using powerful nanomagnets in a technique called magnetic resonance force microscopy
In a 3d stack of nanomagnets, the researchers have implemented a so-called majority logic gate which could serve as a programmable switch in a digital circuit.
Gates made from field-coupled nanomagnets work in an analogous way, with the reversal of polarity representing a switch between Boolean logic states,
So-called domain walls generated there are able to flow through magnetic wires under the control of surrounding nanomagnets.
The most basic building blocks, the individual nanomagnets, are comparable in size to individual transistors. Furthermore, where transistors require contacts and wiring,
nanomagnets operate purely with coupling fields. Also, in building CMOS and nanomagnetic devices that have the same function for example
1 billion of these nanomagnets were placed in a honeycomb pattern on a flat substrate. In total
the nanomagnets covered an area spanning five-by-five millimeters. Initially, the scientists studied the material and its magnetic properties at room temperature.

Packing a sufficient number of nanomagnets onto a chip meant aligning them perpendicularly, but that vertical orientation negated the switching effects of tantalum."
This material made of nanomagnets might well be refined for electronic applications of the future--such as for more efficient information transfer.
A synthetic material--created from 1 billion nanomagnets--assumes different aggregate states depending on the temperature:
the researchers say that this is possible with the nanomagnets. Honeycomb of nanomagnets The magnets are only 63 nanometres long and shaped roughly like grains of rice.
The researchers used a highly advanced technique to place 1 billion of these tiny grains on a flat substrate to form a large-scale honeycomb pattern.
The nanomagnets covered a total area of five by five millimetres. Thanks to a special measuring technique, the scientists initially studied the collective magnetic behaviour of their metamaterial at room temperature.
the researchers might influence these magnetic phase transitions by altering the size, shape and arrangement of the nanomagnets.
The measurements the researchers used to reveal the magnetic orientation of the nanomagnets, and therefore the properties of the metamaterial, can only be conducted exclusively at PSI.
#Small tilt in magnets makes them viable memory chips UC Berkeley researchers have discovered a new way to switch the polarization of nanomagnets,
This image taken from a computer simulation shows nanomagnets tilted at various angles, with the white regions indicating greater angles of tilt.
Packing a sufficient number of nanomagnets onto a chip meant aligning them perpendicularly but that vertical orientation negated the switching effects of tantalum. e found that by tilting the magnet just 2 degrees was enough you get all the benefits of a high-density magnetic switch without the need for an external magnetic field,
#Tilted nanomagnets open door for advances in computing The research, published in the Proceedings of the National Academy of Sciences,
In its latest research, the team discovered that by tilting the nanomagnets slightly they could be aligned in close proximity yet retain the desired properties. e found that by tilting the magnet-just 2 degrees was enough-you get all the benefits of a high-density magnetic switch without the need for an external magnetic field,
