Tlue specific heat of (Sr -Ca)RttO3 systena xvas ttueastrred by aua adiabatic tnethod utilizing a heat-pulse techttiqtre. Tire v?tlues of electronic sjcecific laeat coefficient 7 change frona3Ol11J/IIIOIK' for SrRuO3 to 82l11J/IIIOIK' f'or C2lRL103 throtrgh ;+ za?atxittatruaa value of' arlcotrt100 IIIJ / molK' for Sro.z Cao.sRtr0.?. A strong upturn in the C / T vs T' ctrrve at loxv teraujcertttvtreshas been oloserved f'or p?tr?tzaaargnetic Sr0.zCag.gRtr03 and CaRtrO3. Tlais beharvior is qttantita-Lively explained by the spin-fltrcttr?rtion theory of' the ititaerarnt-electrora raaagtuetisun, sttggestingthat this systerta possibly changes f'rouaa intertnedi;rte itiraer'?tnt f'errotaaagnet of' SrRtrO3, tlrrotrghweakly itinerant ferrornagnet, to nearly f'errozt?agnetic naetal of' C;rRuO3.
