摘要	The polycrystalline La0.7Sr0.3MnO3 films were deposited on SiO2/Si substrates by pulsed laser deposition (PLD), and the temperature gap between Curie temperature (T-C) and insulator-metal transition temperature (T-IM) was tuned successfully by the deposition temperature and its influence on the LFMR properties was investigated. The results showed that the T-C was sensitive to the Mn3+/Mn4+ ratios, whereas the T-IM was sensitive to the microstructures in the LSMO films. The LFMR properties of the LSMO films were enhanced with increasing the Delta T values (Delta T = T-C - T-IM). Our results provide an effective way to modulate the functional properties of LSMO films by modulating the temperature gap between T-C and T-IM. (C) 2016 Elsevier B.V. All rights reserved.
