Query: Designing a fully-compensated half-metallic ferrimagnet   Recent experimental work on Mn2RuxGa demonstrates its potential as a
compensated ferrimagnetic half-metal (CFHM).Here we present a set of
high-throughput ab initio density functional theory calculations and detailed
experimental characterisation, that enable us to correctly describe the nominal
Mn2RuxGa thin films, in particular with regard to site-disorder and defects. We
then construct models that accurately capture all the key features of the
Mn-Ru-Ga system, including magnetic compensation and the spin gap at the Fermi
level. We find that electronic doping is neccessary, which is achieved with a
Mn/Ga ratio smaller than two. Our study shows how composition and
substrate-induced biaxial strain can be combined to design the first
room-temperature CFHM.
