Low-field magneto-transport property of La0.5Sr0.5MnO3 thin films deposited at low temperature by laser ablation. Materials Letters 50 (2-3) : 97-102. ScholarBank@NUS Repository. | Abstract: | The low-field magneto-transport property of polycrystalline La0.5Sr0.5MnO3 (LSMO) thin films deposited on quartz wafers by pulsed laser ablation at various temperatures is investigated. The film is of mixed amorphous and polycrystalline microstructure, depending on the depositing temperature. The low-field magneto-transport property of the thin films can be explained in terms of the two-channel model where the insulating channels and metallic channels coexist. Enhanced low-field magnetoresistance for the samples deposited from 570°C to 600°C in which nano-crystal phase is embedded in the amorphous matrix is demonstrated. © 2001 Elsevier Science B.V.
