Influence of Sr content on CMR effect in polycrystalline La1-xSrxMnO3 thin films
Santrauka
The magnetoresistance of thin polycrystalline La1-xSrxMnO3 films deposited on lucalox substrate using metal organic chemical vapor deposition technique was investigated in pulsed magnetic fields up to 18 T in the temperature range 100-320 K. The influence of film preparation conditions, ambient temperature variation and Sr content is analyzed in order to determine the optimal conditions for the design of CMR-B-scalar magnetic field sensor based on thin manganite film, operating at room temperature.
