A full-Heusler alloy Ti2NiGa have been investigated by first-principles calculations. The electronic structures and magnetic properties have been obtained. The compound is predicted to be a new half-metal ferrimagnet. The calculations show that there is an energy gap in the minority spin of the band structures, whereas the other spin is strongly metallic, which results in a complete spin polarization of the conduction electrons at the Fermi level. This is the obvious feature of a half-metal. The compound has a total magnetic moment of 3.0 µB per unit cell on first-principles calculations which is in excellent agreement with the Slater–Pauling (SP) rule. The magnetic moments of Ti (A) atom and Ti (B) atoms are different. This difference comes from different atom coordination surroundings of Ti (A) and Ti (B) atoms in crystal structure.
