The electrical transition temperature and magnetoresistance prediction of LaSr2Mn2O7 bilayered manganite

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.
