The effect of Ca-doping on the structural, magnetic, electrical, and thermal transport properties has been investigated in Dy1−xCaxVO3(0⩽x⩽0.2) ceramics. Substituting Ca2+for Dy3+leads to a shrinkage of lattice due to the introduction of V4+with a smaller ionic radius. The parent compound DyVO3undergoes three spin/orbital ordering (OO/SO) transitions with decreasing temperature at TOO, TSO1and TSO2, respectively. Increasing the doping level of Ca decreases TSO1, the magnetization above TSO1and below 50K, whereas increases TSO2, indicating the Ca-doping has a suppressing effect on the ordering state in DyVO3system. The thermopower of DyVO3decreases sharply near TOOwhile it is not observed in the Ca-doped samples. The result shows that the x=0.05 Ca-doping is sufficient to melt the OO state in DyVO3system. Both the thermopower and resistivity decrease significantly with increasing the Ca-doping content. The decreased thermopower is suggested to originate from the combined effect of the increased carrier concentration and decreased spin/orbital degeneracies.
