Effect of anisotropy on the transport properties of layered high-temperature superconductors with extended magnetic and nonmagnetic defects. (English) Zbl 07325410

Summary: Transport properties of anisotropic superconductor with point, columnar and columnar tilted defects have been analyzed using Monte-Carlo method. It was shown that for columnar tilted defects the critical current dependence on anisotropy \(\gamma\) weakens as \(\gamma\) increases and vanishes at certain \(\gamma \). The \(S\)-type nonlinearity of current-voltage characteristics has been shown for three-dimensional vortex system in presence of ferromagnetic defects.
