Magnetic studies of the lightly Ru doped perovskite rhodates Sr(Ru,Rh)O${}_3$

Abstract

The solid solution between the ferromagnetic metal SrRuO${}_3$ and the enhanced paramagnetic metal SrRhO${}_3$ was recently reported [K. Yamaura et al., Phys. Rev. B 69 (2004) 024410], and an unexpected feature was found in the specific heat data at $x$=0.9 of SrRu${}_{1-x}$Rh${}_x$O${}_3$. The feature was reinvestigated further by characterizing additional samples with various Ru concentrations in the vicinity of $x$=0.9. Specific heat and magnetic susceptibility data indicate that the feature reflects a peculiar magnetism of the doped perovskite, which appears only in the very narrow composition range 0.85$<$$x$$\le$0.95.
