First principles investigation of the structural, electronic and magnetic properties study of cobalt and the hydrides CoHx (x = 1, 2) show significant volume expansion effect versus Co-H bonding. As hydrogen is incorporated in the cobalt lattice, the density of states undergoes gradual modifications within the valence band and particularly near the Fermi level. A resulting strong reduction of magnetization characterizes the dihydride whereas the monohydride is revealed as a strong ferromagnet, like Co.< Réduire
