Abstract
The magnetic anisotropies of obliquely evaporated Co films were studied using ferromagnetic resonance. The coercive force (Hc) increases rapidly beyond the incidence angle of η=60°. The remanence ratio (Mr/Ms) along the parallel axis at 0° is 0.55-0.7 and comes to a minimum at η=30--60°. For 1000-Å films deposited at η=75°, oblique anisotropy field of Hk1=4.9 kOe, in-plane anisotropy field of Hk2=3 kOe and tilt angle of α=28° were observed; this film has Hc=800 Oe and Mr/Ms=0.95.
