摘要
With various pulse laser energy (E (pulse)), La2/3Ca1/3MnO3:Ag (x) [La1-x Ca (x) MnO3 (LCMO):Ag (x) , x = 0.04, wt%] films were prepared on vicinal cut LaAlO3 substrates by the pulsed laser deposition technique. It is found that laser-induced voltage (LIV) of LCMO:Ag-0.04 films was improved and enhanced by E (pulse). With E (pulse) increasing, figure of merit (F (m)) and anisotropic Seebeck coefficient (Delta S) of LCMO:Ag-0.04 films reached the maximum value of 109.8 mV/ns and 0.29 mu V/K for E (pulse) = 300 mJ. The results suggested that the LIV enhancement of LCMO:Ag-0.04 films was due to Seebeck tensor improvement, the high crystallization and oxygen balance in LCMO:Ag-0.04 films.
