摘要：
The effects of Gd3+ ion doping on the lattice structure and magnetism properties of polycrystalline SmFeO3 were investigated by X-ray diffraction (XRD) and magnetic characterization. Both the magnetic susceptibility and saturation magnetization were significantly enhanced due to the larger spin number of Gd3+. The low doping sample of Sm0.95Gd0.05FeO3 showed great enhancement of magnetic energy product, which may be attributed to the local exchange of different grains.
