Demagnetization by rapid spin transport

The fact that an ultrashort laser pulse is capable of demagnetizing a ferromagnetic layer in a jiffy has been well-known since approximately 1996. What we don't yet understand, however, is how exactly this demagnetization ...

Ferroelectric oxides do the twist

(Phys.org) -- Some materials, by their nature, do what we want them to do -- notably, the ubiquitous, semiconducting silicon found in almost every electronic device. But sometimes, naturally occurring materials ...
