Fabrication of La1-xMnO3+δ (x=0, 0.15) thin films on Si substrates via chemical solution deposition (CSD)

摘要：

La1-xMnO3+δ(x=0,0.15) thin films are fabricated successfully on single crystal Si (h00) substrates using chemical solution deposition method (CSD), LaMnO3+δfilms with (h00) orientation and La0.85MnO3+|δfilms with random orientation. The results show that temperature can obviously affect the orientation and crystallization of LaMnO3+δfilms. Moreover, it is found there exist an insulator-metal transition in the LaMnO3+δfilms, which can be attributed to the oxygen excess. La-deficient can improve crystallization quality and the microstructure of the film. For the La0.85MnO3+|δfilms, show an obvious low field magnetoresistance (LFMR), which is beneficial to practice application.
