characterization of thermal conductivity and diffusivity in presence of model uncertainty, Inv. Prob. in Sci. and Eng., sous presse.
CoPt equiatomic alloy orders according to the tetragonal L1(0) structure which favors strong magnetic anisotropy. Conversely, magnetism can influence the chemical ordering. We present here ab initio calculations of the stability of the L1(0) and L1(2) structures of Co-Pt alloys in their paramagnetic and ferromagnetic states. They show that magnetism… (More)
