Dielectric, electrical and infrared studies of �?-Fe2O3 prepared by combustion method

[摘要] This paper reports the electrical and spectroscopic investigation of the gamma ferrite synthesized through combustion route. The electrical study and dielectric behaviour showed a typical ferrite nature for the samples. The $gamma ightarrow alpha $ transition is observed from the electrical conductivity data. Infrared spectral study showed the transition of a typical ferrite. The effect of the presence of ð›�?-impurities in ð›�?-Fe₂O₃ is also explained here.
