The magnet that didn't exist

In 1966, Japanese physicist Yosuke Nagaoka predicted the existence of a rather striking phenomenon: Nagaoka's ferromagnetism. His rigorous theory explains how materials can become magnetic, with one caveat: the specific conditions ...

Dynamic pattern of skyrmions observed

Cu2OSeO3 is a material with unusual magnetic properties. Magnetic spin vortices known as skyrmions are formed within a certain temperature range when in the presence of a small external magnetic field. Currently, moderately ...

Affordable multiferroic material

Toyohashi University of Technology has developed a novel liquid process for fabrication of an affordable multiferroic nanocomposite film in collaboration with Japan Fine Ceramics Center, National Institute of Technology Ibaraki ...

Theory explains ferromagnetic superconductor behavior

Researchers from France and Russia have offered a theoretical explanation for the behavior of a recently discovered material combining superconducting and ferromagnetic properties. The new theoretical model also predicts ...

Physicists discover new type of spin waves

Current technologies for information transfer and processing are challenged by fundamental physical limits. The more powerful they become, the more energy they need, and the more heat is released to the environment. Also, ...
