Abstract :
In this paper, the magnetic hysteresis loops and ferromagnetic resonance (FMR) spectra are used to study the magnetic properties of Tb/Cr/Fe ultrathin films. Our results show that the saturation magnetization of the Tb/Cr/Fe film is still kept or even higher than that of Fe. Meanwhile, the magnetization dynamic damping constant is largely enhanced.
