Investigation on the structural, electrical and magnetic properties of layered perovskite manganite DySr 2 MnCrO 7

The layered perovskite oxide DySr2MnCrO7 has been prepared by the standard ceramic method. The powder X-ray diffraction studies suggest that the phase crystallizes with tetragonal unit cell in the space group I4/mmm. The electrical transport properties show that the phase is an electrical insulator and the electrical conduction in the phase occurs by a 3D variable range hopping mechanism. The magnetic properties suggest that the ferromagnetic interactions are dominant.
