New ways to construct contactless magnetic gears

18-Feb-2016 - The new milk frother you are using to prepare your cappuccino is likely using magnetic gears. Magnetic gears transmit rotary motion like mechanical gears but instead of teeth they use magnetic attraction and repulsion between rotating magnets. Dr Johannes Schoenke, a postdoctoral scholar at the ...

Ultrafast uncoupled magnetism in atoms

A new step towards computers of the future

14-Sep-2015 - Future computers will require a magnetic material which can be manipulated ultra-rapidly by breaking the strong magnetic coupling. A study in which Swedish and German scientists demonstrate that even the strongest magnetic coupling may be broken within picoseconds. This will open up an exciting ...

Argonne scientists pinpoint mechanism to increase magnetic response of ferromagnetic semiconductor

EuO may help usher in next generation of microelectronics

27-Feb-2009 - When squeezed, electrons increase their ability to move around. In compounds such as semiconductors and electrical insulators, such squeezing can dramatically change the electrical- and magnetic- properties. Under ambient pressure, Europium oxide becomes ferromagnetic only below 69 Kelvin, ...
