Abstract

Normal and superconducting properties of ceramic samples of Pb₂Sr₂Y_1-xCa_xCu₃O_8+δ have been investigated in the wide compositional range of 0≦x≦0.8 and δ∼0. The superconducting transition temperature T_c appears in samples of x≧0.15 and takes a maximum value (T_{c, onset}=83 K, T_{c, zero}=75 K) at x=0.5. This is discussed in relation to x-dependences of the electrical resistivity, the Hall coefficient, the magnetic susceptibility, the upper critical field and the activation energy of the resistive tail in a magnetic field. It is found that these properties of Pb₂Sr₂Y_1-xCa_xCu₃O_8+δ are very similar to those of other high-T_c superconductors with pyramidal CuO₂ layers such as Bi₂Sr₂Ca_1-xY_xCu₂O_8+δ.
