(Phys.org)—Research in spintronics (short for spin transport electronics – the study of the electron's intrinsic spin and associated magnetic moment in solid-state devices) continues to be focused on methods for exercising ...
(Phys.org) —Sometimes mathematical theories have implications that extend far beyond their original purpose. This situation holds true for the four-color theorem, which was originally used by cartographers hundreds of years ...
Today's world, rapidly changing because of "big data", is encapsulated in trillions of tiny magnetic objects - magnetic bits - each of which stores one bit of data in magnetic disk drives. A group of scientists from the Max ...
