Magnetic anisotropies of obliquely evaporated Co films

The magnetic anisotropies of obliquely evaporated Co films were studied using ferromagnetic resonance. The coercive force (H/sub c/) increases rapidly beyond the incidence angle of /spl eta/=60/spl deg/. The remanence ratio (M/sub r//M/sub s/) along the parallel axis at 0/spl deg/ is 0.55-0.7 and comes to a minimum at /spl eta/=30--60/spl deg/. For 1000-/spl Aring/ films deposited at /spl eta/=75/spl deg/, oblique anisotropy field of H/sub k1/=4.9 kOe, in-plane anisotropy field of H/sub k2/=3 kOe and tilt angle of /spl alpha/=28/spl deg/ were observed; this film has H/sub c/=800 Oe and M/sub r//M/sub s/=0.95.
