Magnetic recording with light and no heat on garnet

A strong, short light pulse can record data on a magnetic layer of yttrium iron garnet doped with Co-ions. This was discovered by researchers from Radboud University in the Netherlands and Bialystok University in Poland. ...

Novel state of matter: Observation of a quantum spin liquid

A novel and rare state of matter known as a quantum spin liquid has been empirically demonstrated in a monocrystal of the compound calcium-chromium oxide by team at HZB. According to conventional understanding, a quantum ...

Revealing the nature of magnetic interactions in manganese oxide

For nearly 60 years, scientists have been trying to determine how manganese oxide (MnO) achieves its long-range magnetic order of alternating up and down electron spins. Now, a team of scientists has used their recently developed ...

New physics and application of antiferromagnet uncovered

The research group of Professor Hideo Ohno and Associate Professor Shunsuke Fukami of Tohoku University has studied the control of magnetization using a current applied to heterostructures comprising an antiferromagnet. They ...

Paper proposes method to create gravitational fields

Producing and detecting gravitational fields at will using magnetic fields, controlling them for study, working with them to produce new technologies—it sounds impossible, but Prof. André Füzfa of Namur University has ...

Level repulsion in quantum magnets

Neutron measurements at Oak Ridge National Laboratory's Spallation Neutron Source are giving physicists new insight into the behavior of quantum magnets. A research team led by Young-June Kim from the University of Toronto ...
