We study electronic transport through a ferromagnet normal-metal ferromagnet system and we investigate the effect of hyperfine interaction between electrons and nuclei in the normal-metal part. A switching of the magnetization directions of the ferromagnets causes nuclear spins to precess. We show that the effect of this precession on the current through the system is large enough to be observe...

We study spin-dependent transport in a suspended carbon nanotube quantum dot in contact with two ferromagnetic leads and with the dot’s spin coupled to the flexural modes. We consider a spinvibrational interaction inducing spin-flip processes between the two Zeeman levels of the dot due to spin-orbit interaction or a magnetic field gradient. The inelastic vibration-assisted spin-flips give rise...

FeRhCrSi shows unconventional magnetic and transport properties. It belongs to one of the rare spintronic material classes, namely, spin semimetals. Transport measurements reveal its semimetallic nature, which is further confirmed by $a\phantom{\rule{0}{0ex}}b$ $i\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}t\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}o$ calculation...

It is experimentally established that charge current flowing in a channel with spin-momentum locking such as topological insulator surface states or Rashba interfaces induces a spin voltage, which can be electrically measured with a ferromagnetic contact along the current path. Using this fact in conjunction with Onsager reciprocity arguments, we make the surprising prediction that the anti-par...
