    • Abstract

       

      New Ruddlesden-Popper (RP) type phase LaSr2MnCrO7 has been synthesized by ceramic method. Rietveld profile analysis shows that the phase crystallizes with tetragonal unit cell in the space group I4/mmm. The electrical resistivity of the phase has been measured in the temperature range of 10-300 K using Leybold closed cycle helium cryostat. The phase shows insulator-metal (I-M) transition at low temperature, the phenomenon often associated with giant magnetoresistance. 3D variable range hopping governs the electrical conduction in the insulator region above the I-M transition temperature. Magnetic susceptibility of the phase has been measured in the temperature range of 100-300 K. Magnetic studies suggest that the phase is ferromagnetic.
