IS Y2BaCuO5 INCLUSION EFFECTIVE PINNING SITE IN YBa2Cu3O7?

PINNING ENHANCEMENT OF YBa2Cu2O7–d THIN FILMS WITH Y2BaCuO5 PARTICULATES

A comparison study is given of a typical superconducting YBa2Cu3O7 d (Y123) film and a Y123 film containing a nonsuperconductingY2BaCuO5 (Y211) phase nanoparticulate dispersion. The inclusion of the second phase nanoparticulates was for the express purpose of increasing superconducting film’s magnetic pinning strength with the resultant improved in-field critical current density. LaAlO3 substra...

ISLAND GROWTH OF Y2BaCuO5 NANOPARTICLES IN (211~1.5 nm/123~10 nm)XN COMPOSITE MULTILAYER STRUCTURES TO ENHANCE FLUX PINNING OF YBa2Cu3O7–δ FILMS

Effective vortex pinning in MgB2 thin films

We discuss the pinning properties of MgB2 thin films grown by pulsed-laser deposition (PLD) and by electron-beam (EB) evaporation. Two mechanisms are identified that contribute most effectively to the pinning of vortices in randomly oriented films. The EB process produces low defected crystallites with a small grain size providing enhanced pinning at grain boundaries without any degradation of ...
