• The magnetic anisotropy of iron-cobalt ferrite is studied by means of ferromagnetic resonance. The cubic magnetic anisotropy K_1/M and the uniaxial magnetic anisotropy K_T/M induced by heat treatment in magnetic field are measured in the temperature range between 70℃ and 250℃. The secondary peak observed in the ferromagnetic resonance of iron-cobalt ferrite are explained by the domains having different orientation of uniaxial magnetic axis. From the experimental results g-factor of iron-cobalt ferrite is determined to be 2.86. The temperature dependence of g-factor has not been observed within limits of errors.
