Campbell penetration depth in low carrier density superconductor YPtBi
Campbell penetration depth in low carrier density superconductor YPtBi
Magnetic penetration depth, ${\ensuremath{\lambda}}_{m}$, was measured as a function of temperature and magnetic field in single crystals of low carrier density superconductor YPtBi by using a tunnel-diode oscillator technique. Measurements in zero DC magnetic field yield London penetration depth, ${\ensuremath{\lambda}}_{L}(T)$, but in the applied field the signal includes the Campbell …
