Abstract
The effects of the substitution of Cr with Co on microstructure, phase composition, structure, magnetic, and electrical properties in (0 ⩽ x ⩽ 1) alloys was investigated to identify the compositions with the potential to exhibit half-metallicity. The microstructural and structural studies revealed that only alloys with x ⩾ 0.5 exhibited the desired single phase L21 full Heusler alloy structure. Both the saturation magnetization (Ms) and Curie temperature (TC) were found to increase with the increase in Co concentration. The experimentally measured Ms values are in good agreement with the Slater–Pauling rule. The electrical resistivity measurements in the temperature range 10–300 K gives indirect evidence of half-metallic behaviour in these alloys at low temperatures. The temperature range in which the half-metallic behaviour was observed also increased with an increase in Co concentration.
