中文摘要	In the present work, the modified angular dependences of coercivities in inhomogeneous magnets are analyzed with respect of the ratio K1'/K2' of reduced anisotropy constants in defect region of grains. Results indicate that below the value of 0.9 of ratio Kl'/K2', the H(c)(THETA))/H(c)(0) increases with deviation angle between external field and c-axis of grain without a minimum. Above the value of 0.9 of K1'/K2', the angular dependence of H(c)(THETA)/H(c)(0) has a minimum. The angular dependences of coercivities for NdFeB and SmFeN magnets have no minimum, which reflect the existence of inhomogeneous areas in grains where the anisotropy constants are greatly reduced. Meanwhile our results clearly indicate that the nucleation model agrees to the experimental results much better than the pinning model for SmFeN epoxy resin bonded magnet.
