Temperature dependence of the magnetic penetration depth in the vortex state of the pyrochlore superconductor, Cd2Re2O7.
We report transverse-field and zero-field muon spin rotation and relaxation studies of the superconducting rhenium oxide pyrochlore, Cd2Re2O7. Transverse-field measurements (H=0.007 T) show line broadening below T(c), which is characteristic of a vortex state, demonstrating conclusively the type-II nature of this superconductor. The penetration depth is seen to level off below about 400 mK (T/T...
متن کاملMuon-spin rotation measurements of the magnetic penetration depth in the iron-based superconductor Ba1xRbxFe2As2
Measurements of the magnetic penetration depth � in the Fe-based superconductor Ba1−xRbxFe2As2 (x=0.3, 0.35, 0.4) were carried out using the muon-spin rotation (�SR) technique. The temperature dependence of � is well described by a two-gap s + s-wave scenario with a small gap Δ1 � 1–3 meV and a large gap Δ2�7–9 meV. By combining the present data with those previously obtained for RbFe2As2 a dec...
متن کاملMagnetic Penetration Depth Measurements in Cuprate Superconductors
We examine recent results on measurements of the magnetic penetration depth in cuprate superconductors, with particular emphasis on our results obtained with the microstrip and parallel-plate resonator techniques. The results show that the magnetic penetration depth temperature dependence in YBa2Cu307-a is not consistent with a simple scaled weak-coupled BCS temperature dependence. We present t...

متن کاملMagnetic field dependence of the penetration depth of d-wave superconductors with strong isolated impurities
A d-wave superconductor with isolated strong non-magnetic impurities should exhibit an upturn in the penetration depth at low temperatures [1]. Here we calculate how an external magnetic field supresses this effect.
