Penetration depth of a superconducting superlattice.
We have measured the magnetic-flux expulsion of a superconducting superlattice and related it to the Meissner penetration depth. The temperature dependence of the penetration depth is in quantitative agreement with theoretical expectation based on mean-field theory. The zerotemperature penetration depth is found in excellent, quantitative agreement without adjustable parameters with theoretical...

متن کاملDetermination of the magnetic field penetration depth in YBa2Cu307-d superconducting films by polarized neutron reflectometry
Polarized neutron reflectometry was used for the direct measurement of the magnetic-field penetration depth in a high-temperature (HT,) superconducting film. Two scattering geometries were used. The deduced neutron scattering length density profile gave an exact picture of the composition of the film. The fit to the spin-asymmetry yielded a magnetic-penetration depth of 1400 2 100 A at a temper...
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 کاملCharge Stripes and Antiferromagnetism in Insulating Nickelates and Superconducting Cuprates
Neutron and X-ray scattering studies have provided strong evidence for coupled spatial modulations of charge and spin densities in layered nickelates and cuprates. The accumulated results for La2−xSrxNiO4+δ are consistent with the strongly-modulated topological-stripe concept. Clues from Nd-doped La2−xSrxCuO4 suggest similar behavior for the cuprates. The experimental results are summarized, an...
