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…
An electron spin injection driven, paramagnetic solid-state MASER device
S. M. Watts, B. J. van Wees
In response to an external, microwave-frequency magnetic field, a paramagnetic medium will absorb energy from the field that drives the magnetization dynamics. Here we describe a n…
Unified description of bulk and interface-enhanced spin pumping
S. M. Watts, J. Grollier, C. H. van der Wal +1
The dynamics of non-equilibrium spin accumulation generated in metals or semiconductors by rf magnetic field pumping is treated within a diffusive picture. The dc spin accumulation…
