摘要：

A new 1212 type (Pb,Cd) based cuprate superconducting system (Pb0.5Cd0.5)Sr-2(Tb1-xCax)Cu2O7 has been prepared. It crystallizes in a tetragonal lattice with cell parameters: a = 3.822 Angstrom, c = 11.951 Angstrom and space group P4/mmm (for x = 0). The samples exhibit bulk superconductivity with a transition temperature of 19 K.
