Randomness in atomic disorder and consequent squandering of spin-polarization in a ferromagnetically fragile quaternary Heusler alloy FeRuCrSi

Shuvankar Gupta, Sudip Chakraborty, Vidha Bhasin +7

Ru${}_{2-x}$Fe${}_x$CrSi ( 0 $<$ x $<$1) system is theoretically predicted to be one of the very few known examples of robust half-metallic ferromagnet with 100\% spin polarization. Si…
