The electronic structures of Ti2 NbSb with Hg2CuTi structure and TiZrNbSb with LiMgPdSn structure are investigated using first-principles calculations.The results indicate that Ti2NbSb is a fully compensated ferrimagnetic spin-gapless semiconductor with an energy gap of 0.13eV,and TiZrNbSb is a half-metallic fully compensated ferrimagnet with a half-metallic gap of 0.17eV.For Ti2NbSb,the total energy of the Hg2CuTi structure is 0.62eV/f.u.higher than that of the L21 structure,which is the ground state,and for TiZrNbSb,the total energy of the structure considered in this work is only 0.15eV/f.u.larger than that of the ground state.Thus both of them may be good candidates for spintronic applications.
