摘要：
Epitaxial La1−xPbxMnO3 (LPMO) thin films, grown on (100) SrTiO3 substrates by laser ablation technique at different temperatures between 600 and 850°C, have been characterized for electrical and magnetic properties. The temperature dependence of resistivity showed that the metal-insulator transition temperature (TMI) decreases with increasing substrate temperature, which has been attributed to decrease in Pb content in the filsm. The YBa2Cu3Ox/La1−xMnO3 heterostructures, exhibiting both superconductivity and ferromagnetism, have been fabricated.
