Abstract

We report magnetic behavior of a dilute ferromagnetic alloy Ni1-xMnx, 0≪x≪25%. Magnetic circular dichroism (MCD) is used to examine the local magnetic moment on each element, and superconducting quantum interference device magnetometry is used to evaluate the magnetization of the alloy as a whole. Both MCD and hysteresis loops show a collapse in moment at x≈15% measured at 100 K. The Mn doping appears to disturb the long-range ordering of the host nickel spins which, in the concentration range studied, is a precursor disordered ferromagnet prior to a spin-glass phase.
