| Abstract: | MnBiRE thin films possess larger magneto optical Kerr rotation. It will be likely a good information storage material. MnBiRE(RE=Ce,Pr,Nd and Sm) were prepared by vacuum vaporation method. The influence of temperature on the coercivity and Kerr rotation was investigated. The written and readout characteristics of the samples were analyzed and compared with that of quadri layer structure TbFeCo films. |
