In conclusion, we have used first-principles FPLO method to
investigate the structural, electronic and magnetic properties of
Ba2CeCoO6 compound. This compound has a cubic crystalstruc-
ture with space group Fm 3m. The FM phase is found to be more
stable than PM phase. At the equilibrium lattice constant, our
calculations indicate that this compound is a half-metallic ferromagnet with an integermagnetic moment of 1.00 μB per
formula unit and half-metallic gap of 0.18eV. The half-metallicities
of Ba2CeCoO6 can be preserved when the lattice constants are
compressed by 11.1% with respect to the equilibrium lattice. Using
the quasi-harmonic Debye model, the heat capacity, bulk modulus,
Debye temperature, and thermal expansion coefficient under
temperature and pressure are investigated. The Ba2CeCoO6 compound
may be a promising material for future spintronic
application.
