Abstract
The half-metallic ferromagnet CoLa2O4 was predicted based on density function theory. Its magnetic and electric properties were studied systematically. Results show that CoLa2O4 has half-metallicity and its molecular magnetic moment is 3.00 µB, which is lower than 4.0 µB of Fe3O4. CoLa2O4 is more sensitive than Fe3O4 in the same applied field. La-ions have little spin polarization. The electronic structures of a Co-ion and a La-ion are a1g 1↑a1g 1↓t1u 3↑t1u 3↓eg 2↑eg 2↓t2g 3↑ and a1g 1↑a1g 1↓t1u 3↑t1u 3↓ t2g 3↑t2g 3↓eg 2↑eg 2↓eg 2*↑eg 2*↓, respectively.
