Structural and magnetic properties of layered perovskite manganite LaCaBiMn2O7

The layered perovskite oxide, LaCaBiMn2O7, has been prepared by the conventional aqueous solution precipitation method. The powder X-ray diffraction studies suggest that the phase crystallizes with tetragonal unit cell in the space group I4/mmm. The magnetic properties suggest that the ferromagnetic...
