英文摘要	With the wide use of electromagnetic devices in GHz frequency band, the exploration of microwave soft magnetic materials with high permeability at GHz band has attracted much attention [1]. The previous studies have demonstrated that the good microwave magnetic properties can be achieved for the soft magnetic materials with easy-plane anisotropy, and the product of initial permeability and natural resonance frequency for the easy-plane material can be described as [2]: (μ1-1)fr=(2γMs/3)(Hθ/H)2, (1) where γ'=2.8 GHz/kOe, Hθ and Hp are out-of-plane anisotropy field and in-plane anisotropy field. The Eq. (1) has theoretically pointed out the high Ms and ratio of Hθ/Hp are preferable to get the good microwave magnetic property. Compared to the widely reported easy-plane soft magnetic particles with flake shape and easy-plane Co2Z particles, rare earth-transition metal compounds with easy-plane anisotropy which induced by strong magneto crystalline anisotropy are presumed to have more superior microwave magnetic properties because of their large saturation magnetization and high ratio of Hθ/Hp. © 2015 IEEE.
