Résumé

Specific heat, transport and reversible magnetization measurements have been performed on high quality (K,Ba)BiO₃ single crystals (T_c ∼ 31 K). Calorimetric measurements up to 16 T show that the transition line between the superconducting and normal states has a strong anomalous positive curvature. The reversible magnetization deviates strongly from the standard London model above 0.8T_c emphasizing the original nature of the superconducting transition in this system.
