Abstract

The London penetration depth, lambdaab(T), is reported for thin films of the electron-doped superconductor Pr2-xCexCuO4-y at three doping levels (x = 0.13, 0.15 and 0.17). Measurements down to 0.35 K were carried out using a tunnel diode oscillator with excitation fields applied both perpendicular and parallel to the conducting planes. For all samples and both field orientations lambdaab(T) showed power law behavior implying a superconducting gap with nodes.
