摘要：

The presence of strong vortex fluctuation effects in two families of layered high-temperature superconductors (HgBa2CuO4+delta and Tl2Ca2Ba2Cu3O10+delta) 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 lambda(ab), upper critical field H(c2), and Ginzburg-Landau parameter kappa(ab) (With magnetic field perpendicular to the copper oxide planes) of these materials.
