  • La1-XCaXMnO(LCMO),La1-XPbXMnO(LPMO) and La1-XSrXCoO(LSCO) thin films were prepared with laser pulse deposition technique in order to investigate the laser induced thermoelectric voltage signal which affected by temperature.The laser induced thermoelectric voltage signals of La1-XCaXMnO3(LCMO),La1-XPbXMnO3(LPMO) and La1-XSr-XCoO3(LSCO) thin films were measured at 290K~340K temperature range by using lock-in amplifier.The signal-temperature coefficients(STC) of three CMR thin films were defined and compared.It was found that the LSCO demonstrated positive and smallest STC,while LCMO showed largest and negative STC.
