Magnetic Field Dependence of the Spin Susceptibility on Conventional <i>s</i>-wave Superconductor LaRu<sub>4</sub>P<sub>12</sub> Revealed by <sup>31</sup>P-NMR and <sup>139</sup>La-NMR
The magnetic field dependence of the spin part of Knight shift, which is proportional to the superconducting-state spin susceptibility, was investigated at two nuclear sites, $^{31}$P and $^{139}$La in a conventional s-wave superconductor LaRu$_4$P$_{12}$. After the analyses, we confirmed that the superconducting-state spin susceptibility is proportional to magnetic field, and connects to the normal-state spin susceptibility smoothly. This is a textbook example, when the superconductivity is broken with the orbital pair-breaking effect.
