Electron spin resonance in GdxY1-xIr2

Abstract
Electron spin resonance measurements are reported for the (Gd, Y)Ir2 pseudobinary series. The results indicate that the ESR bottleneck of gadolinium can be broken by dilution with yttrium. The parameters relating to the relaxation rates have been determined by fitting the data to Hasegawa's theory (1959). The results are shown to be consistent with the behaviour of other gadolinium-transition metal compounds.
