摘要：

We analyzed the enhancement of the Gilbert damping constant due to spin pumping in noncollinear ferromagnet/nonmagnet/ferromagnet trilayer systems. We show that the Gilbert damping constant depends both on the precession angle of the magnetization of the free layer and on the direction of the magnetization of the fixed layer. We find the condition to be satisfied to realize strong enhancement of the Gilbert damping constant.
