文摘

The series of Er(Co_1−yX_y)₂ compounds (X = p-electron element) with y≤0.05 was investigated regarding to magnetic, elastic, transport, and thermodynamic properties. A significant increase of Curie temperature (from 31 up to 52K) caused by substitutions of p-electron elements for Co in ErCo₂ (T_C
