The Co-Y (Cobalt-Yttrium) system

Instability of the Co magnetic state in Y2Co7-based compounds: Effect of alloying for Y- and Co-sites

“…According to our X-ray diffraction measurements, parent Y 2 Co 7 compound has the lattice parameters a = 4.995 Å, c = 36.145 Å, in agreement with the previously reported data [8]. Concentration dependence of the a and c lattice parameters of all series of compounds are shown in Fig.…”

Correlation of microstructure and catalytic activity of crystalline Ni–Co–Y alloy electrode for the hydrogen evolution reaction in alkaline solution

“…This range extends on the Y-rich side, but the extent was not determined. Y 2 Co 17 melts congruently (1360 • C) and a homogemeity region was suggested at high temperature [47]. For Y 2 Co 17 phase, the two inter-related structures hR57-Th 2 Zn 17 and hP38-Th 2 Ni 17 have been described.…”

Thermodynamic modelling of the Co–Y system

“…The region 50-75 at.% Y was clarified by Grover et al [23]. The Co-Y system was reviewed by Wu and Chuang [24].…”

“…The magnetic properties of the intermetallic compounds in the Co-Y system were studied by many investigators [21,26,[32][33][34][35][36][37][38][39][40][41] and reviewed by Givord and Lemaire [39], Buschow [1] and Wu and Chuang [24], respectively. The values of the critical temperature for magnetic ordering and the Bohr magnetic moment of the compounds, which are used in the present work, are listed in Table 2.…”
