Abstract

We report a B11 NMR measurement on the recently discovered superconductor Li2Pd3B. The nuclear spin lattice relaxation rate 1 T1 shows a well-defined coherence peak just below Tc(H=1.46T)=5.7K, and the spin susceptibility measured by the Knight shift also decreases below Tc. These results indicate that the superconductivity is of conventional nature, with an isotropic gap. Our results also suggest that the p-electrons of boron and the d-electrons of palladium that hybridize with boron p-electrons are primarily responsible for the superconductivity.
