Abstract
(Received 30 July 2010; revised manuscript received 23 November 2010; published 10 January 2011)It is proposed to use a jump-noise process in magnetization dynamics equations to account for thermal batheffects.Itisshownthatinthecaseofasmalljump-noiseprocess,theLandau-LifshitzandGilbertdampingtermscan be analytically derived as deterministic (average) effects caused by the jump-noise process. Simple formulasfor the damping constant are derived that relate it to the scattering rate of the jump-noise process and elucidateits dependence on magnetization. Generalized
