Epitaxial thin films of heavily doped perovskite manganite (La1−xSrxMnO3 or LSMO with x ≥ 0.5) were successfully fabricated onto SrTiO3(001) single crystal substrates by chemical solution deposition. The electrical resistivity and the Hall coefficient were measured from 200 to 673 K. The temperature coefficient of resistance reached a minimum at 0.6 ≤ x ≤ 0.7. A high-temperature stability test showed that the LSMO thin films could be used up to 673 K. This study has shown that LSMO thin films are good candidates as high-temperature resistive materials that can be used in SiC power electronics.
