Abstract
The EuNi2(Si1-xGex)2 system exhibits a temperature- and field-induced valence transition from Eu3+ to Eu2+ in the concentration range 0.75≤x≤0.85. In this study, we performed magnetization measurements on compounds with 0.5≤x≤0.75 in ultra-high fields up to 300 T generated by explosive compression of magnetic flux. We observed a jump of the magnetization, indicating a field-induced valence change from Eu3+ to Eu2+ for each compound. The critical field increases linearly with decreasing x and reaches a value of 225 T for x = 0.5.
