Abstract

Mn0.5Co0.5NH4PO4. 2H2O has been synthesized at room temperature by coprecipitation method. The structure was determined on X-ray powder diffraction data leading to a crystallization in the space group Pmn21 with cell parameters a = 5.568 ± 0.011 Å, b = 6.158 ± 0.008 Å and c = 19.38 ± 0.04 Å. TG-DTA curves, suggest the loss of water hydration (2 H2O).The IR spectrum is characteristic of H2O, PO4 3- and NH4 + radicals. The magnetic study confirms the presence of two ions Co2+ and Mn2+ with ratio ½ - ½ and exhibits an antiferromagnetic comportment..

Keywords

XRD, TG-DTA, IFTR, Manganese-Cobalt Ammonium Phosphate dihydrate, Antiferromagnetism. Low dimensionality.
