Abstract
We present Raman scattering studies of the magnetic, electronic, and structural properties of Ca2-xSrxRuO4 as functions of temperature and Sr substitution. Raman spectra from Ca2RuO4 reveal a two-magnon scattering response for T<TN and an increase of the electron-phonon interaction strength through TN. The two-magnon energy at low temperature is relatively insensitive to Sr substitution. In contrast, Sr substitution causes a much more dramatic renormalization of the two-magnon energy and linewidth with increasing temperature toward TN. Moreover, substitution of Sr for Ca results in a significant increase in the electron-phonon interaction strength.
