Experimental Spin Ratchet
Marius V. Costache, Sergio O. Valenzuela
Spintronics relies on the ability to transport and utilize the spin properties of an electron rather than its charge. We describe a spin rachet at the single-electron level that pr…
Electrical detection of spin pumping: dc voltage generated by ferromagnetic resonance at ferromagnet/nonmagnet contact
M. V. Costache, S. M. Watts, C. H. van der Wal +1
We describe electrical detection of spin pumping in metallic nanostructures. In the spin pumping effect, a precessing ferromagnet attached to a normal-metal acts as a pump of spin-…
Large cone angle magnetization precession of an individual nanomagnet with dc electrical detection
M. V. Costache, S. M. Watts, M. Sladkov +2
We demonstrate on-chip resonant driving of large cone-angle magnetization precession of an individual nanoscale permalloy element. Strong driving is realized by locating the elemen…
Electrical detection of spin pumping due to the precessing magnetization of a single ferromagnet
M. V. Costache, M. Sladkov, S. M. Watts +2
We report direct electrical detection of spin pumping, using a lateral normal metal/ferromagnet/normal metal device, where a single ferromagnet in ferromagnetic resonance pumps spi…
On-chip detection of ferromagnetic resonance of a single submicron permalloy strip
M. V. Costache, M. Sladkov, C. H. van der Wal +1
We measured ferromagnetic resonance of a single submicron ferromagnetic strip, embedded in an on-chip microwave transmission line device. The method used is based on detection of t…
Spin accumulation probed in multiterminal lateral all-metallic devices
M. V. Costache, M. Zaffalon, B. J. van Wees
We study spin accumulation in an aluminium island, in which the injection of a spin current and the detection of the spin accumulation are done by means of four cobalt electrodes t…
