Abstract The high coercivity of 26.2 kOe for SmCo 5 nanoflakes are obtained by multistep (three steps) surfactant-assisted ball milling. magnetic properties, phase structure and morphology studied VSM, XRD SEM, respectively. results demonstrate that the three step ball-milling can keep more complete crystallinity (relatively less defects) during process milling compared with one energy ball-milling, which enhances texture degree coercivity. In addition, mechanism also temperature dependence demagnetization curves aligned nanoflakes/resin composite, result indicates magnetization reversal could be controlled co-existed mechanisms pinning nucleation.
