xNi/10NiO-NiFe2O4(x=5,10,17) cermets and those doped with 1% BaO(mass fraction) were prepared by cold isostatic pressing at 200 MPa and sintering in nitrogen at
Lattice constants, total energies and densities of states of transition metals Fe, Ru and Os with BCC, FCC and HCP structures were calculated by the GGA+PBE fun
