Cattle respond to magnetic fields from power lines

(AP) -- High-voltage power lines mess with animal magnetism. Researchers, who reported last year that most cows and deer tend to orient themselves in a north-south alignment, have now found that power lines can disorient ...

Disappearing homing pigeon mystery solved

Homing pigeons are usually remarkably efficient navigators, however, on rare occasions, things go drastically wrong. So, when Jon Hagstrum of the US Geological Survey read in his local newspaper about two races when pigeons ...

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 ...

Simultaneous imaging of ferromagnetic and ferroelectric domains

An international team led by researchers from the NIST Center for Nanoscale Science and Technology have discovered a new way to simultaneously image both the ferromagnetic and the ferroelectric domain structures of multilayer ...

A new-structure magnetic memory device developed

The research group of Professor Hideo Ohno and Associate Professor Shunsuke Fukami of Tohoku University has developed a new-structure magnetic memory device utilizing spin-orbit- torque-induced magnetization switching.

Observation of skyrmions in a ferromagnet with centrosymmetry

Researchers from the National Institute of Materials Science (NIMS) have used Lorentz electron microscopy to show that magnetic skyrmions are spontaneously formed as nanomagnetic clusters in a ferromagnetic manganese oxide ...

Fast magnetic writing of data

Magnetic data storage has long been considered too slow for use in the working memories of computers. Researchers at ETH have now investigated a technique by which magnetic data writing can be done considerably faster and ...
