Synthesis two Crystalline CompoundsSr2-xSmxCoO4Belonging to the RUDDLESDEN-POPPER Series by Partial Sustention of Strontium (Sr) with Samarium (Sm) and Study their Crystal Structure and some Physical Properties

The oxides ofSr2-xSmxCoO4(X=1 ,1.25) were Synthesised using the ceramic method and the effect of partial sustention of Sr with Sm in crystal lattice of compound Sr2CoO4has been studied. The phases and structures were studied using powder x-ray diffraction and HRTEM(High Resolution Transmission Electron Microscopy)
