Abstract
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 and no spin-glass interaction could be detected. The Mn moment results in the disappearance of superconductivity at \ensuremath{\simeq}2 at.% Mn while Ni-Zr and Fe-Zr glasses remain superconducting up to 60 at.% Ni and 28 at.% Fe. The superconducting properties of the host amorphous Zr-Ni and Zr-Cu films were similar to those of glasses obtained by melt spinning.
