Abstract
Ca1-xSrxVO3 is an ideal system for studying bandwidth effects. The substitu tion of a Ca2+ ion for a Sr2+ ion reduces the bandwidth due to bucklings of V-O-V bond angles. The Wilson ratio R-W similar or equal to 2 substantiate s strong electron correlations in this system, while the effective mass sho ws moderate values against the critical enhancement of the Brinkmann-Rice p icture.
