The temperature dependence of saturation magnetization and perpendicular magnetic anisotropy for 16 and 18% Cr-Co sputtered films was studied. The following were found: (i) the Curie temperatures of films are higher than those of bulk alloys; (ii) the perpendicular anisotropy constant increases after being heated to 400°C; and (iii) it changes from positive to negative at about 640°C.
