Keywords: | Curie temperature; Magnetoresistance; Thin films- Ferromagnetic | Issue Date: | 2001 | Journal Volume: | 226-230 | Journal Issue: | PART I | Start page/Pages: | 690-692 | Source: | Journal of Magnetism and Magnetic Materials | Abstract: | The La0.7 Sr0.3MnO3 (LSMO) film is deposited successfully onto a MgO (001) substrate by using a magnetron DC sputtering system. The θ-20 X-ray diffraction pattern is detected to investigate the structure of the deposited LSMO film. According to the experimental temperature dependent magnetization result, the Curie temperature of the sample is 364.8 K. The magnetic hysteresis curve with a coercivity of 17 Oe was found for the LSMO film at 300K, meanwhile, a significant magnetoresistance was observed. With these properties at room temperature, the LSMO-based devices might be very suitable for practical applications. © 2001 Published by Elsevier Science B.V. |
