Half-metallic Heusler alloys have attracted considerable attention due to their unique electronic and magnetic properties, making them promising candidates for spintronic applications. In this study, we investigate the structural and magnetic properties of the novel Fe₁.₅VGe alloy and its parent compound Fe₂VGe. Heusler compounds are known for exhibiting ferromagnetism originating from specific atomic ordering rather than intrinsic magnetic elements, enabling high spin polarization essential for advanced electronic devices. The reduction in Fe content is expected to significantly influence the electronic structure, magnetic moment, and exchange interactions within the lattice. A comparative analysis between Fe₁.₅VGe and Fe₂VGe is performed to understand the effect of compositional variation on their crystallographic stability and magnetic behavior. The results indicate noticeable changes in magnetic ordering and structural parameters, suggesting tunable magnetic properties driven by chemical substitution. These findings contribute to the broader understanding of half-metallic systems and highlight the potential of Fe–V–Ge-based Heusler alloys for future spintronic device applications, including magnetic sensors and high-density data storage technologies
