The electrical transition temperature and magnetoresistance prediction of LaSr2Mn2O7 bilayered manganite

Abstract

In this paper, the resistivity of bilayer manganite LaSr2Mn2O7 around the metal–insulator-like transition was systematically calculated as a function of temperature and applied magnetic field. A typical mathematical function (Gauss function) was used for fitting the experimental data. The theoretical values simulated in this work such as – metal–insulator transition temperature (Tp) and maximum resistivity (ρmax) showed promising agreement with the experimental data.
