The effect of ruthenium doping upon the temperature of the ferromagnetic-to-paramagnetic (,FM-PM) transition in a series of La0.8Sr0.2Mn1-xRuxO3 (0 < x < 0.2) has been studied by electron spin resonance (ESR). The onset of the FM-PM transition has been determined from the variation of the effective g factor with temperature. TC was shown to increase from 310 K for x =0 up to a maximum value at 352 K for x = 0.15.
