Abstract

Delocalized quasiparticles in the vortex state of an overdoped high-Tc superconductor was probed by 63Cu nuclear magnetic resonance (NMR). The spin Knight shift (Ks) and nuclear spin-lattice relaxation rate (1/T1) in the vortex state were reported as a function of magnetic field up to 28 T in the superconductor. Results showed that for temperatures below Tc the K and 1/T1 increased substantially with increasing field.
