Weyl fermions discovered in another class of materials
A particular kind of elementary particle, the Weyl fermions, were first discovered a few years ago. Their specialty: they move through a material in a well ordered manner that practically never lets them collide with each other and is thus very energy efficient. For the very first time, scientists at the Paul Scherrer Institute PSI have experimentally proved their existence in another type of material: a paramagnet with intrinsic slow magnetic fluctuations.

Spin-polarized electrons on demand
Spintronics, in the future, could replace electronics. Different from electronics, where whole electrons are moved, here it is a matter of manipulating the electron spin.

Both are possible with a single electron pump, as scientists of the Physikalisch-Technische Bundesanstalt have, together with colleagues from Latvia, now shown. (2009-01-21)

Ferromagnetic nanoparticle systems show promise for ultrahigh-speed spintronics
