Magnetic damping in perpendicular [Pt/Co]3/MnIr multilayers
Source abstract
Abstract
Abstract We studied the influence of Pt, Co and MnIr layer on the exchange bias field HE and coercive field HC in perpendicular exchange-biased [Pt/Co]3/MnIr multilayers by magneto-optical Kerr effect. As the thickness of the Pt layer increases, the perpendicular magnetic anisotropy constant Ku first increases and then reaches to saturation, which is resulted from the competition between perpendicular anisotropy and interfacial short-range interaction. The saturation damping constant α0 of the sample increases from about 0.062 to 0.122 when the Pt thickness increases from 0.5 nm to 1.5 nm. However, α0 increases with the decrease of Co thickness. We attributed both of these mainly to spin pumping effect.
