Multinary Metal Alloys Of The Heusler, Half-Heusler, Dilute Magnetic Semiconductors, And High Entropy Families: How Would Spin Make A Choice?

Multinary alloys from the half-Heusler, Heusler, dilute magnetic semiconductors and magnetic high entropy alloys have been investigated for their properties to accommodate quantum spin states and touch Curie temperatures above room temperature as utterly desired for spintronic devices. Co, Mn and Fe are the core elements in the alloys studied here. High structural ordering has been found in Co-based Heusler alloys, followed by equiatomic high entropy alloys with close atomic radii also cobalt based. Curie points between 400 degrees C and 900 degrees C were found in all materials.
