Modeling magnetic evolution and exchange hardening in disordered magnets: The example of Mn${}_{1-x}$Fe${}_x$Ru${}_2$Sn Heusler alloys

Elizabeth Decolvenaere, Emily Levin, Ram Seshadri +1

We demonstrate how exchange hardening can arise in a chemically-disordered solid solution from a first-principles statistical mechanics approach. A general mixed-basis chemical and…
