Synthesis, structural and electrical-transport characterization, and first-principles investigations of the quaternary Heusler compound NiCrMnAl

We report experimental and first-principles studies of bulk NiCrMnAl alloy. X-ray diffraction of annealed, arc-melted sample shows a cubic Heusler phase. The (111) and (200) superlattice peaks are absent, indicating site disorder. Annealing restores the (400) peak and improves cr...
