Local Mn moment in amorphous Mn-Zr alloys.
01 January 1984
The well known existence of a spin-glass interaction in Cu- Mn and Au-Mn alloys prompted the investigation of a possible spin-glass interaction in Mn-Zr alloys which can be prepared in the amorphous state over a wide Mn concentration range. The spin-glass interaction was not observed. However, while Ni, Co and Fe display no local magnetic moment when alloyed with Zr in metallic glasses, Mn has a local moment in Mn-Zr, Mn-Zr-Cu and Mn-Zr-Ni alloys. The moment decreases as Mn increases from 1 to 67 at. % as a result of increasing antiferromagnetic order.
