Abstract

Delocalized quasiparticles in the vortex state of an overdoped high-T_c superconductor was probed by ⁶³Cu nuclear magnetic resonance (NMR). The spin Knight shift (K_s) 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 T_c the K and 1/T₁ increased substantially with increasing field.
