制备两年后的高矫顽力TbFeCo薄膜的结构和性质以及飞秒激光诱导超快磁化动力学研究，徐初东，陈志峰，通过飞秒时间分辨磁光Kerr光谱技术结合振动样品磁强计（VSM），研究了以SiO2为基底无保护层的TbFeCo磁光薄膜，在室温空气下玻璃器皿中�

An uncoated TbFeCo film on glass substrate exposed to dry air for 2 years is studied using magneto-optical polar Kerr spectroscopy and vibrating sample magnetometry (VSM). The out-of-plane hysteresis loop by VSM is found to become slanted and meanwhi
