Magnetic 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 کاملCritical fluctuations in superconductors and the magnetic field penetration depth.
The superconducting transition is studied within the one-loop RG in fixed dimension D = 3 and at the critical point. A tricritical behavior is found and, for κ > κc, an attractive charged fixed point, distinct from that of a neutral superfluid. The critical exponents of the continuous transition are evaluated and it is shown that the anomalous dimension of the gauge-field equals unity. This imp...
متن کاملEffect of welding parameters on penetration depth in FB-TIG welding of 5083 aluminum alloy
In the present study, effect of current, welding speed and preheat temperature during FB-TIG welding of AA5083 aluminum alloy was studied. Using the Taguchi method, 9 different tests were designed to investigate the effect of welding parameters on the penetration depth. Consistent with predictions, increasing the current and preheat temperature, and reducing the welding speed led to an increase...
متن کاملThe Kosztin-Leggett Nonlocal Effect on the Magnetic Penetration Depth in Superconductors with Nodes in the Gap
Penetration depth measurements have played a very fundamental role in the study of the gap symmetry of all unconventional superconductors. For instance, from magnetic penetration depth measurements it was first suggested the dwave symmetry for the energy gap in high critical temperature superconductors (HTSC) [1]. It is expected that, for superconducting energy gaps with nodes on the Fermi surf...
