摘要：

The Gilbert damping parameter, G, determined from ferromagnetic resonance (9 - 92 GHz), is presented as a function of concentration, x, for single crystalline FexCo1-x alloy films prepared by rf sputtering. On the Fe-rich side, a plateau-like behavior is found for G(x), extending to about x = 0.5. In addition, the g-factor, g, is shown to exhibit a very similar dependence, in agreement with theoretical calculations which relate these two quantities via the spin-orbit coupling. It is seen that the compositional dependence of both G(x) and g(x) cannot be described by a simple interpolation between the values for the pure elements.
