Correlation between structural, magnetic and electric properties of La0.5Ca03Te0.2MnO3 sample synthesis by sol-gel method
The structural, magnetic and electric properties of the sample have been investigated. The crystal structure estimated via X-ray powder diffraction indicates that this system is characterized by a single phase and crystallizes in the orthorhombic structure with space group Pnma. The results of Hirshfeld surface indicate that the intermolecular electrostatic interactions are in short range verifying so that the magnetic interactions have been still in short range. The values of critical exponents obtained from the resistivity and from magnetic measurements are very close to those predicted based on the mean field tri-critical model. (C) 2017 Elsevier B.V.
