LaBaCaCu3O7 (La:1113) and NdBaCaCu3O7 (Nd:1113) compounds are synthesized by solid state reaction route. Both compounds crystallize in tetragonal structure. Four probe resistivity measurements showed that superconducting transition temperature (Tc) is 73 K and 41 K respectively for La:1113 and Nd:1113 compounds. Considering the fact that for RE:123 (REBa2Cu3O7) compounds the Tc hardly depends upon the choice of RE (Rare earth, except Ce, Pr and Tb), the current nearly two fold increase in Tc of La:1113 when compared to Nd:1113, warrants serious discussion.
