摘要：
The transport properties of the electron-doped cuprates Ln2-xCexCuO4 (Ln=Pr, Nd and Sm) single crystals are investigated under hydrostatic pressure up to 2 GPa. The effects of pressure on both the c-axis (rho(c)) and the in-plane (rho(ab)) resistivity are measured from room temperature down to the superconducting state. It is found that at 300 K, dln rho(ab)/dP almost-equal-to dln rho(c)/dP almost-equal-to -3% GPa-1. The pressure does not change the temperature dependence of the normal state resistivity, which at high temperature in both directions follows a rho approximately A(P)T2 law, but the coefficient A(P) decreases as pressure is increased. Moreover, we have found that for any lanthanide host (Pr, Sm and Nd) the onset of superconductivity does not change with pressure (P < 2 GPa).
