摘 要:<正>NdTbCo/Cr amorphous films with high perpendicular magnetic anisotropy were prepared onto glass substrates by rf magnetron sputtering.The effects of Nd substitution on the magnetic and magneto-optical properties of TbCo/Cr films were investigated.It was found that partial Tb substitution by Nd would increase the saturation magnetization and the Kerr rotation angle,change the temperature dependence of magneto-optical characteristics.These results can be explained by the ferrimagnetic structure of the rare earth-transition metal alloy.When the magnetic layer composition was(Nd0.265Tb0.735)31Co69,a saturation magnetization of 247 emu/ cm3 and a coercivity of 3.8 kOe at room temperature could be obtained.
