dc.description.abstract | Colossal magnetoresistance is closely related to (bur is not) the abrupt change of electrical resistivity in the vicinity of Curie temperature, which is caused by the temperature-dependent paramagnetic-ferromagnetic phase transition and concurrent change of electrical conducting mechanism. A model equation based on the effective medium theory is presented to explain the abrupt change of resistivity in the vicinity of Curie temperature of La-Ca-Mn-O (LCMO). II is assumed that LCMO is in the form of mixture of ferromagnetic and paramagnetic phase in the magnetic transition region. The main ingredients of the equation are a simple effective medium theory and a Function For thr temperature-dependent fraction of ferromagnetic phase. This model fits very well to the measured resistance-temperature curves of La0.7Ca0.3MnO3. (C) 2000 Elsevier Science B.V. All rights reserved. | - |
