Penetration Depth Studies of Unconventional Superconductors
The magnetic penetration depth λ of various unconventional superconductors have been measured down to ~0.1 K using a tunnel-diode based, self-inductive technique at 21 and 28 MHz. The samples measured are the heavy-fermion superconductors CeCoIn5 and PrOs4Sb12, the rare-earth borocarbides RENi2B2C …

Penetration depth measurements of organic superconductors
The temperature dependence of the magnetic penetration depth (λ) has been measured in single crystals of fully deuterated κ-(ET)2Cu[N(CN)2]Br. This material separates into superconducting (SC) and antiferromagnetic (AFI) phases. The relative amounts of SC and AFI phases has been shown to depend on …
