ESR measurements for Gd(Αl1-x,zGex) and Gd(Αl1x- xSbx) pseudobinary
systems with x G 0.15 are presented. In all investigated compounds a marked
change in thermal broadening of the line width was observed in temperature
lower than 300 K. Using obtained results tle bottleneck parameter was calculated
as a function of concentration x.
