Crystalline and Magnetic Properties of Cr₂MnAl

In recent years, Heusler alloys have attracted much attention in the scientific community because of their potential for application in the field of spintronics. This is due to their uncommon properties, such as half-metallicity and spin-gapless semiconductivity. We have synthesized one predicted half-metallic alloy, Cr₂MnAl, using methods of stoichiometric engineering, arc melting, and annealing at high temperatures. The as-prepared Cr₂MnAl alloy shows a cubic crystal structure with the A2 type disorder. The magnetic hysteresis curve recorded at 100°C from the as-prepared sample shows a small saturation magnetization of about 0.2 emu/g. We will also include the effect of doping Co, Fe, V, Ti in the Cr site followed by high temperature annealing in this presentation. Additionally, the results from our first principal calculations will also be presented.
