Generation of coherent spin-wave modes in yttrium iron garnet microdiscs by spin–orbit torque

HIGHLIGHTS

• who: M. Collet from the Université Grenoble Alpes, des Martyrs, Grenoble, France, Institute of Physics, Kazan Federal University, Kazan, Russian have published the Article: Generation of coherent spin-wave modes in yttrium iron garnet microdiscs by spin–orbit torque, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS of 27/01/2016
• what: The authors show clear evidence of coherent spin-orbit torque-induced auto-oscillation in micron-sized yttrium iron garnet discs of thickness 20 nm. For this, the authors compare the autooscillations observed in the 4- and 2-mm microdiscs.
