Magnetic properties of (misch metal, Nd)-Fe-B melt-spun magnets

Magnetic properties of (misch metal, Nd)-Fe-B melt-spun magnets

The effect of replacing Nd with misch metal (MM) on magnetic properties and thermal stability has been investigated on melt-spun (Nd1-xMMx)13.5Fe79.5B7 ribbons by varying x from 0 to 1. All of the alloys studied crystallize in the tetragonal 2:14:1 structure with single hard magnetic phase. Curie te...
