  We have studied magnetic and transport properties in polycrystalline
CaRu1-xScxO3 for 0 =< x =< 0.20 in order to clarify the substitution effects of
a non-magnetic trivalent ion. We find that a ferromagnetic transition with Tc =
30 K is observed in Sc-substituted samples. The composition dependence of the
Curie-Weiss temperature implies that the magnetic susceptibility has a
paramagnetic contribution with negative theta and a ferromagnetic contribution
with positive theta. The field dependence of magnetization at 2 K is also
understood as a summation of the ferromagnetic and paramagnetic components.
These results suggest that CaRu1-xScxO3 is a non-uniform magnetic system. The
relationship between the ferromagnetic ordering and the transport properties is
also discussed.
