Anomalous anti-damping in sputtered β-Ta/Py bilayer system
Anomalous decrease in effective damping parameter α(eff) in sputtered Ni(81)Fe(19) (Py) thin films in contact with a very thin β-Ta layer without necessitating the flow of DC-current is observed. This reduction in α(eff), which is also referred to as anti-damping effect, is found to be critically de...
