Structural, microstructural and magnetic properties of amorphous/nanocrystalline Ni63Fe13Mo4Nb20 powders prepared by mechanical alloying

► The amorphous/nanocrystalline Ni63Fe13Mo4Nb20 magnetic powders were prepared by mechanical alloying. ► The saturation magnetization decreases and the coercivity increases as a result of the electronic interactions and the grain size reduction. ► The use of amorphous alloy is due to the lower magnetic losses and higher electrical resistivity compared with other magnetic material
