Abstract

The site-specific magnetic properties of thin films of the Heusler compound Mn2RuxGa, 0.6<x<1.0, are studied using x-ray absorption and dichroism spectroscopy. There is evidence of half metallicity up to x=0.7, and compensation of the Mn 4a and 4c moments in this range, leading to a zero-moment half metal. We also also discuss the effect of substrate-induced strain on the magnetic properties. By tuning the biaxial strain, simultaneous perfect magnetic compensation and half-metallic character is achievable at, below, or above room temperature.
