dc.descriptionWe report the temperature dependence of transport and magnetic properties of La$_{1-x}$Ca$_x$VO$_3$ for x = 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5. The system exhibits an insulator-to-metal transition concomitant with an antiferromagnetic-to-paramagnetic transition near x = 0.2 with increasing substitution. Disorder effects are found to influence the low temperature transport properties of both insulating and metallic compositions near the critical concentration. At higher temperatures, the resistivity of the metallic samples is found to exhibit either a $T^{1.5}$ or a $T^2$ dependence depending on the composition. The molar susceptibility for the metallic samples indicate substantial enhancements due to electron correlation.
