Vortex movements parallel and perpendicular to twin boundaries seen through the Nernst and Seebeck effects of YBa2Cu3O7−δ

Three dimensional analyses of flux pinning centers in Dy-doped YBa2Cu3O7−x coated superconductors by STEM tomography

“…Two main structural characteristics of both samples are the existence of particles and the twin boundaries throughout the YBCO layer. Twin boundaries are common planar defects in YBCO related films [40][41][42] and their significant effect on superconductive properties of YBCO has been reported in many studies [43][44][45][46][47]. As can clearly be seen from Fig.…”

Guiding of vortices and the Hall conductivity scaling in a bianisotropic planar pinning potential

“…[10][11][12][13][14][15][16] Two main reasons stimulated these studies. First, in some high-T c superconductors ͑HTSC's͒ twins can easily be formed during the crystal growth.…”

“…First, in some high-T c superconductors ͑HTSC's͒ twins can easily be formed during the crystal growth. [11][12][13][14][15][16][17] Second, in layered HTSC's the system of interlayers between parallel ab planes can be considered as a set of unidirectional planar defects which provoke the intrinsic pinning of vortices. 1 As the pinning force in a PPP is directed perpendicular to the pinning planes, 1 the vortices tend to move along these planes if the driving force has a nonzero component in any in-plane direction.…”
