Evidence of large anisotropy in the magnetization of Na0.35CoO2.1.3H2O quasi-single-crystal superconductors

Abstract

Quasi-single crystals (up to 2x2x1 mm3) of Na0.35CoO2.1.3H2O-superconductor have been grown. Magnetization M(H, T) and M(T, H) curves with magnetic field approximately parallel and perpendicular to c-axis indicates on large anisotropy, comparable with Bi-based high-temperature superconducting (HTS) phases.
