Magnetic Studies on New Mixed-Valence Phosphates Zn2+Fe23+(P2O7)2 and Zn0.52+Cu0.52+Fe23+(P2O7)2
Structural studies of Zn 2+ Fe 2 3 + (P 2 O 7 ) 2 and Cu 0.5 Zn 0.5 Fe 2 (P 2 O 7 ) 2 were made using powder X-ray diffraction and refined by Rietveld method. Both phosphates crystallize in an orthorhombic structure with Pnma space group. Magnetometry measurements showed that below T N = 5.6 (1), Zn...
