摘要：
The anisotropy of Ba-ferrite (BaFe10.4Co0.8Ti0.8O19) particulate media having a perpendicular orientation was studied using ferromagnetic resonance. An effective anisotropy field H(k) of 2.87 kOe and a gyromagnetic ratio gamma/2-pi of 2.76 GHz/kOe were obtained. Also, the magnetocrystalline anisotropy K(u) of 1.2 x 10(6) erg/cm3 was obtained for the Ba-ferrite particles.
