Magnetic Field Induced Density of States in Superconducting MgB${}_2$: Measurement of Conduction Electron Spin-Susceptibility

F. Simon, A. Janossy, T. Feher +7

The magnetic field dependence of the spin-susceptibility, ${\chi }_s$ was measured in the superconducting state of high purity MgB${}_2$ fine powders below 1.3 T. ${\chi }_s$ was determine…
