摘要：

Modification of hydrogen reduction of mechanically alloyed Ni-ferrite led to well dispersed spherical FeNi nanoparticles with superior magnetic properties. The as-milled powder was reduced in hydrogen atmosphere at 600 degrees C for 1 h. Salt-matrix utilization during the reduction showed itself as a well barrier to the particle sintering and growth. As the results of the modified process, shape of the particles was changed, their size was decreased and their soft magnetic properties were remarkably improved as evidenced by SEM, TEM, XRD and VSM.
