dc.description.abstract | Recent experimental work on Mn

Ga 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 a detailed
experimental characterization that enable us to correctly describe the nominal Mn
2
Ru
x
Ga 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 necessary, 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 a ferrimagnetic half metal with a
compensation point close to room temperature. | en |
