CRYSTALLIZATION AND MAGNETIC PROPERTIES OF AMORPHOUS Nd_6Fe_(81)B_(13)ALLOY

The magnetic properties and the crystallization and its influence on the magnetic and struc- tural properties for rapidly quenched amorphous Nd_6Fe_(81)B-(13) alloy have been studied.The low temperature magnetic properties,the Curie temperature and the crystallization behavior are discussed.A small addition(6at.-%)of Nd in amorphous Fe-B alloys increases largely the crystallization temperature T_x but causes a decrease of the Curie temperature Tc·A new phase was observed in the sample annealed at 873 K.
