Abstract

Effect of Fe-doping on the structural and magnetic properties of Co₂V₂O₇ compound has been investigated through x-ray diffraction and dc magnetic measurements. Undoped Co₂V₂O₇ undergoes a paramagnetic to antiferromagnetic transition at 6 K and this transition temperature is found to be shifted towards higher temperature with increasing Fe-doping. Isothermal magnetization data as a function of external field indicates the presence of weak ferromagnetic interaction in otherwise antiferromagnetic compound at 5 K. Fe-doping gradually kills the weak ferromagnetic nature observed for the undoped compound. Paramagnetic nature of all the studied samples above Neel temperature are confirmed from isothermal magnetization data recorded at 50 K.
