Abstract
The step magnetization is observed in spin glass manganites La0.67Ca0.33(Mn , Fe)O-3, and the colossal magnetoresistance larger than 10(4) % (Delta R/R -H) is obtained near the critical field. The micro-origin of the novel step magnetism is attributed to the melting of antiferromagnetic clusters in th e applied magnetic field.
