Magnetic resonance, ac susceptibility and hysteresis-loop measurements are described to demonstrate that a-Fe80Ru10B10 is a concentrated spin glass while a-Fe33Ru33B34 exhibits reentrant magnetism. Concomitantly, it is shown that the temperature dependence of the induced magnetization follows the expressions proposed by us recently.
