ScholarBank@NUS Repository. https://doi.org/10.1088/0953-8984/13/1/302 | Abstract: | Pulsed laser deposition of La0.5Sr0.5MnO3 (LSMO) thin films on quartz wafers at different deposition temperatures has been carried out. The microstructural, electrical and low-field magnetotransport properties of these films are evaluated as functions of the deposition temperature. The film crystallinity depends substantially on the deposition temperature. Significantly enhanced low-field magnetoresistance for the samples deposited from 570 °C to 600 °C, in which amorphous phase and polycrystalline phase coexist, is observed. The electrical and low-field magnetotransport properties of the thin films are explained by the two-channel model where insulating channels of variable-range-hopping conduction and metallic ones coexist. | Source Title: | Journal of Physics Condensed Matter | URI: | http://scholarbank.nus.edu.sg/handle/10635/113077 | ISSN: | 09538984 | DOI: | 10.1088/0953-8984/13/1/302 |
