Anisotropic superconductivity in noncentrosymmetric BiPd
Anisotropic superconductivity in noncentrosymmetric BiPd
We report measurements of London penetration depth $\ensuremath{\lambda}(T)$ for the noncentrosymmetric superconductor BiPd by using a tunnel diode oscillator. Pronounced anisotropic behavior is observed in the low-temperature penetration depth; the in-plane penetration depth ${\ensuremath{\lambda}}_{ac}(T)$ follows an exponential decrease, but the interplane penetration depth ${\ensuremath{\lambda}}_{b}(T)$ shows power-law-type behavior. The superfluid density …
