Phase diagram, vortex dynamics and dissipation in thin films and superlattices of 1:2:3 superconducting cuprates

Abstract

The mixed state of High Temperature Superconductors (HTS) is a new field that allows us to study very interesting and new phenomena related with glassy behavior. There are many topics that could be addressed, but in this paper we are going to deal with two topics. The first one concerning to the single vortex dynamics, and the second one related with the dissipation mechanisms of the vortices and the so-calle d lock-in transition. The former will be studied using the anomalous behavior of the Hall effect in the mixed state with c-axis oriented 1:2:3 films the latter using as an appropriate tool the critical current, the pinning force and the resistivity (dissipation) in the m ixed state of 1:2:3 a-axis oriented superconductor / non-superconductors multilayers.
