Spin-glass-like behaviour of manganese-based amorphous Mn × X alloys (X 3d, 4d, 5d metals) and its dependence on the MnMn interatomic spacing
1991
Abstract The magnetic properties of manganese-based binary amorphous MnX alloys have been investigated for the non-magnetic elements X3d, 4d, 5d metals. In all the alloys except MnY and MnLa the magnetization increases monotonically with decreasing temperature and indicates an effective moment for manganese in the range 0.5–1.8 μg per manganese atom. From a plot of the effective paramagnetic moment p eff vs . the average MnMn interatomic distance D nn we find that spin-glass-like behaviour occurs for p eff ⩾ 1 μ B and D nn ⩾ 3.0 A .
