Microwave magnetic properties of gadolinium-iron films

We have made ferromagnetic resonance measurements on Gd 1- x Fe x films, where x = 0 to 1. The saturation magnetization, g-value, the exchange stiffness constant, the magnetic damping parameter and some surface anisotropy parameters were determined. We find that the exchange decreases rapidly as the...

Description
Summary:We have made ferromagnetic resonance measurements on Gd 1- x Fe x films, where x = 0 to 1. The saturation magnetization, g-value, the exchange stiffness constant, the magnetic damping parameter and some surface anisotropy parameters were determined. We find that the exchange decreases rapidly as the Fe content decreases. The g-values obey the Wangsness relation except near compensation. The exchange-conductivity linewidth broadening is minimal in this system.
