dc.descriptionWe investigate the role of long range ferromagnetic order in the electronic structure of Sr$_{1-x}$Ca$_x$RuO$_3$ using high resolution photoemission spectroscopy. SrRuO$_3$ is a ferromagnetic metal but isostructural, isoelectronic CaRuO$_3$ is an enhanced paramagnet. Surface spectra of CaRuO$_3$ exhibit temperature induced modifications. This is not significant in other compositions. This may be attributed to the structural changes observed in previous studies. Interestingly, the bulk spectra reveal unusual spectral changes exhibiting large decrease in the coherent feature intensity corresponding to only ferromagnetic samples, although the Ru moment is very similar in all the compositions.
