Abstract

The presence of strong vortex fluctuation effects in two families of layered high-temperature superconductors (HgBa2CuO4+δ and Tl2Ca2Ba2Cu3O10+δ) is established from experimental studies of the equilibrium magnetization in the mixed state using the theory of Bulaevskii et al. Detailed information is obtained within the framework of this theory on the London penetration depth λab, upper critical field Hc2, and Ginzburg-Landau parameter κab (with magnetic field perpendicular to the copper oxide planes) of these materials.
