摘要：
The NiFe/FeMn bilayers with different buffer layers (Th or Ta/Cu) were prepared by magnetron sputtering Results show that the exchange coupling field of NiFe/FeMn films with Th buffer is higher than that of the films with Ta/Cu buffer. We analysed the reasons by investigating the crystallographic texture, surface roughness and surface segregation of both films, respectively. We found that the decrease of the exchange coupling fields of NiFe/FeMn films with Ta/ Cu buffer layers was mainly caused by the Cu surface segregation on NiFe surface.
