摘要：
We report the structural, magnetic and electronic properties of quaternary Heusler alloy CoRhTiAl. Room temperature XRD analysis reveals that the alloy crystallizes in B2-type structure instead of perfectly ordered Y-type structure due to 50 % disorder between the tetrahedral sites (Co and Rh) as well as octahedral sites (Ti and Al). The ab-initio simulations with GGA+U method predict a perfectly half-metallic ferrimagnetic nature with a gap in the minority spin-channel and thus, a high spin polarization.
