Magneto-electronic and thermoelectric properties of V-based Heusler in ferrimagnetic phase

We investigated the structural, magneto-electronic, and thermoelectric properties of V 2 CoZ (Z = Ga, and Ge) Heusler alloys using the ab-initio method. The XA-type structure within the ferrimagnetic phase is more energetically stable than other phases through the chemical stability so the negative value of energy formation that both compounds are favorable and synthesizable experimentally. Both compounds' mechanical properties show anisotropic ductile materials. In addition to their half-metallic ferrimagnetic behavior with an integer total magnetic moment, according to magneto-electronic calculations. Boltzmann's transport theory was also used to investigate the thermoelectric response. Our findings show that these Heusler alloys have a lot of potential for thermo-spintronic devices.
