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-…
Spin Accumulation and Spin Relaxation in a Large Open Quantum Dot
E. J. Koop, B. J. van Wees, D. Reuter +2
We report electronic control and measurement of an imbalance between spin-up and spin-down electrons in micron-scale open quantum dots. Spin injection and detection was achieved wi…
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…
Microwave spectroscopy on magnetization reversal dynamics of nanomagnets with electronic detection
J. Grollier, M. V. Costache, C. H. van der Wal +1
We demonstrate a detection method for microwave spectroscopy on magnetization reversal dynamics of nanomagnets. Measurement of the nanomagnet anisotropic magnetoresistance was used…
