Sukhanov A. A. , Ozmanyan Kh. R. , Sandomirskii B. B.
A superconducting transition with = 82-95 ë and Tc (R = 0) = 82-72 ë has been detected in bulk and film samples of Bi(Srj _xCax )2óÉÜï^ synthesized in a solid-phase reaction. The resistance, critical current, and susceptibility were measured as a function of temperature.
