摘要
Specific heat of "single-crystal-like" YBa2Cu3O7-x is measured in magnetic field (B(a)) using adiabatic calorimetry. The field dependence of specific heat near T(c) for B(a) perpendicular-to c axis is found to be about five times lower than that for B(a) parallel-to c axis. The experimental results can be understood quantitatively in terms of the Ginzburg-Landau theory of anisotropic type-II superconductors.
