A ferromagnetic-resonance study was made of the magnetic-anisotropy constant of the polycrystal ferrite spinels CoxNi0_s_r/2 Cu0ib_xl2 Fe204 (x = 0.00, 0.02, 0.04, 0.06 and 0,08). Quenching from a high temperature (950°C) leads to an increase in the positive constant К due to the transfer of arelatively small number of A ferromagnetic-resonance study was made of the magnetic-anisotropy constant of the polycrystal ferrite spinels CoxNi(0,5—x/2) Сu(0,5—x/2) Fe2O4(х=0,00; 0,02; 0,04; 0,06; 0,08). Quenching from a high temperature (950°C) leads to an increase in the positive constant К due to the transfer of arelatively small number of Ni^{2+}ions to the tetrahedral sublattice. The results agree with the data of Pointon, who studied the effect for nickel ferrites containing a slight amount of Co. ions to the tetrahedral sublattice.
