Abstract:

An experimental study was made on the magnetic behaviour of 40∼70 at%Mn-Bi alloys cast with a metal mould, followed by heat treatment in a magnetic field. It was confirmed that the ferromagnetic crystallites are preferentially grown with their magnetically preferred orientation along the applied field direction. The orientation effect is enhanced with decreasing Mn content. The effect of cold rolling on magnetic properties of the oriented samples was also investigated. Particularly with 40 at%Mn-Bi alloy, excellent magnetic properties were obtained when the oriented sample was reheated in a magnetic field after cold rolling.
