CHANGE IN MAGNETIZATION OF CO50GA50 DUE TO ATOMIC DISORDER INDUCED BY QUENCHING FROM HIGH-TEMPERATURES

The intermetallic compound Co50Ga50 is quenched from different high temperatures. By quenching, the atomic disorder at high temperature is conserved. The magnetisation in fields up to 14 T, the lattice parameter, and the vacancy concentration are determined as function of quenching temperature. The results of the magnetisation measurements are compared with magnetisation measurements on CoxGa100-x as a function of Co concentration performed in [1]. The lattice parameter and vacancy concentration are compared with in situ measurements in [2,3]. The measurements are in good agreement with these data previously obtained.
