The step magnetization is observed in spin glass manganites La0.67Ca0.33(Mn,Fe)O3, and the colossal magnetoresistance larger than 104%(ΔR/RH) is obtained near the critical field.The micro-origin of the novel step magnetism is attributed to the melting of antiferromagnetic clusters in the applied magnetic field.
