利用JDP-560C19型超高真空磁控溅射仪,在玻璃衬底上溅射制备NiMn/NiFe双层膜样品,。通过控制NiMn/NiFe双层膜退火温度改变其微观结构,研究样品磁性与退火温度的关系。研究表明,NiMn/NiFe双层膜的矫顽力和交换偏置场均随着退火温度的升高而增大,当退火温度为350℃时,矫顽力和交换偏置场都出现一个峰值,随后随着温度升高,矫顽力和交换偏置场减小。

NiMn/NiFe bilayers are prepared on glass substrates by sputtering method. Different annealing temperature is used in order to change the microstructures and magnetic properties of the samples. It is showed that the coercivity and the exchange bias field of the NiMn/NiFe bilayers are increased when the annealing temperature goes up, at T=350 ℃, a peak is observed, and then the coercivity and the exchange bias field are decreased.
