AbstractQuenching rate dependence of crystallization and magnetic properties of the nanocrystalline materials has been studied. It was found that higher quenching rates result in lowering of activation energy of crystallization and also the size of nanocrystalline grains. Coercive force of the specimen prepared with higher quenching rate is higher, which is attributed to higher surface to volume ratio in the specimens, resulting in a stronger domain wall pinning at the surface.
