Abstract
The structure and magnetic properties of nanocrystalline, two-phase Sm (2)Fe(1)7N(x)+alpha-Fe alloys prepared by mechanical alloying and heat treatment have been studied. Remanence enhancement and single-phase m agnetic behavior were observed in isotropic powders crystallized at lo w temperatures (about 600 degrees C), while crystallization at high te mperatures resulted in two-phase demagnetization curves due to increas e of the grain size of the soft phase. With increasing Sm concentratio n the coercivity increased and the remanent magnetization decreased.
