  • 采用磁控溅射方法制备了分别以Ta和Ta/Cu作为缓冲层的一系列NiFe/FeMn双层膜.实验发现,以Ta为缓冲层的NiFe/FeMn双层膜的交换偏置场比以Ta/Cu为缓冲层的NiFe/FeMn双层膜的交换偏置场大.测量了这两种双层膜的织构、表面粗糙度和表面成分.结果表明,以Ta/Cu为缓冲层时,Cu在NiFe层的上表面偏聚是造成NiFe/FeMn双层膜交换偏置场降低的重要原因.
    The NiFe/FeMn bilayers with different buffer layers (Ta or Ta /Cu) and Ta cover layers were prepared by magnetron sputtering. The results showed that the exchange bias field of NiFe/FeMn films with the Ta buffer was higher than that of the films with the Ta/ Cu buffer .We investigated the crystallographic texture, surface roughness and surface segregation, and demonstrated that the decrease of the exchange coupling field was caused by the Cu surface segregation in NiFe/FeMn films with Ta/ Cu buffer layers.
