Abstract:

We performed dc-magnetization measurements in low magnetic fields on single crystals of Ba1-xKxBiOy BKBO with the different potassium content. The single crystals reveal the superconducting transition at 29 - 31 K. It is shown that the lower critical fields Hsub Cl in crystals amount to 104 Oe x 0.34, 126 x 0.34 and 112 Oe x 0.4. The values of the penetration depth lambda 0 are equal to 2530 A, 2430 A and 2670 A for x 0.34, 0.37, and 0.4, respectively.
