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.
