Abstract

In this paper, we report observation of the vortex lattice above the surface of high-temperature superconductors Pr_{2 - x} Ce_x CuO_{4 - δ} using beta-detected NMR (β-NMR) of ⁸Li⁺ implanted in a 40 nm thick Ag overlayer. The resonance in Ag broadens dramatically below the transition temperature T_c as expected from the vortex lattice in the underlying superconductor. However, the lineshape is nearly symmetric with the absence of a high-field tail and exhibits a slight positive shift of the average field below T_c.
