Abstract

The temperature and field dependences of reversible magnetization in Ba_1-xK_xBiO₃ single crystals (x equals 0.34 and 0.37) were studied. From the vortex fluctuation model the temperature dependence of the penetration depth is determined. The analysis of the experimental data suggests that for (BaK)BiO₃ family of superconductors the thermal fluctuation effects are very small and that an external magnetic field does not cause the reduction of the effective dimensionality of the system.
