Temperature dependence of the magnetization of nanocrystalline Fe/sub 68.5/Co/sub 5/Nb/sub 3/Cu/sub 1/Si/sub 13.5/B/sub 9/ alloy

Increasing attention has been given to nanocrystalline Fe-Nb-Cu-Si-B alloy system. Substitution of Co in the Fe-Nb-Cu-Si-B alloy have a influence on the magnetic properties. To understand the magnetic properties of nanocrystalline Fe
