Relativity shakes a magnet: Researchers from Institute of Physics ASCR demonstrate a new principle for magnetic recording

Abstract

In order to shake a magnet electrically without involving an electro-magnet or another permanent magnet, one has to step out of the realm of classical physics and enter the relativistic quantum mechanics. Researchers from the Institute of Physics, in collaboration with researchers from Cambridge, Nottingham, and Mainz, have discovered a new physical phenomenon that allows manipulating the state of a magnet by electric fields.

Magnetic inside but not on outside: Researchers from the Institute of Physics introduce antiferromagnetic memories

Abstract

Researchers from the Institute of Physics of the Academy of Sciences of the Czech Republic, in collaboration with researchers from Berkeley and Barcelona, have demonstrated that it is possible to use another type of magnetic materials, the so-called antiferromagnets to store information. Antiferromagnetic materials are magnetic inside, however, their microscopic magnetic moments sitting on individual atoms alternate between two opposite orientations.
