    • Abstract


      γ-Fe2O3 synthesized from FeC4H4O4·4H2O has been studied using various techniques. The phase transformation observed by electrical conductivity measurements agrees well with the initial magnetization measurement. The magnetic hysteresis values compare with those ofγ-Fe2O3 samples synthesized using established procedures.γ-Fe2O3 particles obtained were circular in shape showing a well resolved six narrow bands in Mössbauer spectrum. The presence of hydrogen ferrite phase was also confirmed by electrical and magnetic measurements.
