| 摘 要： | 用射频磁控溅射方法在玻璃基片上制备厚度为100 nm的Fe80Pt20薄膜,研究了退火对其结构和磁性的影响。随着退火温度的升高,观察到了Fe80Pt20薄膜从fcc相到可能的hcp相的相变。并且,当退火温度高于653 K时,薄膜的饱和磁化强度和矫顽力都发生显著的变化。不同温度退火薄膜的饱和磁化强度与温度的关系曲线也表明了这一相变。

| Abstract: | The Fe80Pt20 films with thickness of 100 nm have been deposited on glass substrate by RF magnetron sputtering.The influence of annealing was investigated on the phase structure and magnetic property of the films.With increasing annealing temperature,the phase transformation from fcc to hcp was observed.Meanwhile,dramatic changes take place in both saturation magnetization and coercivity of the films when annealing temperature is higher than 653 K.The temperature dependence of the saturation magnetization ha... |
