摘要：
The temperature dependences of the magnetization and magnetic anisotropy of Fe/Pt compositionally modulated multilayered films (CMFs) prepared by RF sputtering were investigated. The magnitude of the surface magnetic anisotropy Ks of Fe/Pt CMFs is nearly equal to that of Co/Pt CMFs at 77 K and at room temperature. The absolute value of the volume magnetic anisotropy Kv of Fe/Pt CMFs is about twice as large as that of Co/Pt CMFs. The Ks obtained from CMFs with thick Fe layers seems to remain nearly constant as the temperature is varied. However, Kv decreases gradually with increasing temperature in the case of Fe/Pt CMFs. The relation between the saturation magnetization and the perpendicular magnetic anisotropy is discussed.
