The laser-induced thermoelectric voltage (LITV) was observed in La_0.9Pr_0.1MnO₃ thin films grown on the vicinal cut LaAlO₃ substrate by pulsed laser deposition for the first time. The detected signals were demonstrated to be originated from the anisotropic Seebeck effect. The largest peak value of the voltage is about 2.4 V, the full width at half-maximum of the temporal voltage peak and the rising time are 300–500 and 40–50 ns, respectively. It is a high quality and efficient material in the LITV family.
