Pinning and creep in layered superconductors
MV Feigel'Man, VB Geshkenbein, AI Larkin - Physica C: Superconductivity, 1990 - Elsevier
The thermal-and disorder-induced effects in the mixed state of a layered high-T c
superconductor (in a field H‖ c) are studied. The flux line lattice is of a quasi-2D type at
sufficiently high field H⪆ H 0 where H 0 is proportional to the mass anisotropy m/M and
estimated to be around 3 T for the Bi-and Tl-based superconductors. At H》 H 0 the FLL melts
at a temperature T m close to the temperature of 2D dislocation-mediated melting. At T> T m
the system is in the normal state. At low temperatures T< T g⋍ T m/In (H/H 0) the system is in …
