Critical Current Density of YBa 2 Cu 3 O 7 − δ Low - Angle Grain Boundaries in Self - Field
A study has been perfomed on the superconducting critical current density Jc flowing across low angle grain boundaries in epitaxial thin films of YBa2Cu3O7−δ (YBCO). The materials studied were dual grain boundary rings deposited on SrTiO3 and containing 2 , 3, 5 and 7 tilt boundaries. The current density in self-field was determined by magnetometric methods at temperatures from 5 K to Tc. We co...
متن کاملCritical Current of Low-Angle Grain Boundaries in High-Tc Superconductors
Dependence of the critical current on the misorientation angle in high-temperature superconductor [001] tilt bicrystal is theoretically examined. We suppose that in the case of relatively small values of the bicrystal misorientation angle θ (θ ≤ 10÷15) the critical current is determined by depinning of vortices, which are locked by edge dislocations aligned along the bicrystal grain boundary. D...
متن کاملStress-driven migration of simple low-angle mixed grain boundaries
We investigated the stress-induced migration of a class of simple low-angle mixed grain boundaries (LAMGBs) using a combination of discrete dislocation dynamics simulations and analytical arguments. The migration of LAMGBs under an externally applied stress can occur by dislocation glide, and was observed to be coupled to the motion parallel to the boundary plane, i.e. tangential motion. Both t...

متن کاملTransition between Low and High Angle Grain Boundaries
Institut für Metallkunde und Metallphysik, RWTH Aachen, 52056 Aachen, Germany Carnegie Mellon University, Pittsburgh PA 15213, USA Abstract The migration of planar, symmetric tilt grain boundaries with different tilt axes was investigated. The driving force for the grain boundary migration was due to an external mechanical stress field. Low as well as high angle grain boundaries can move under ...
