Efeito do tratamento térmico na estrutura cristalina da cerâmica supercondutora SmBa2Cu3O7−δ

Abstract

Samples of SmBa2Cu3O7−d polycrystalline ceramic were prepared by the solid state reaction method, with the purpose of producing superconducting tablets. The precursor was prepared from the calcination of a mixture of samarium oxide (Sm2O3), barium c
