Low temperature 151Eu and 57Fe Moessbauer study of mechanically alloyed EuFeO3

Low temperature 57Fe Moessbauer spectra of mechanically alloyed EuFeO3 prepared by mechanical alloying depicts an interesting transformation in its hyperfine magnetic state, from a triple phase magnetic system at room temperature to a single phase ferromagnetic state at 20 K. The hyperfine magnetic field increased by 12% at 20 K from its room temperature. The isomer shift and quadrupole splitting values exhibit a peak around 200 K. Low temperature 151Eu Moessbauer measurements show that the line-width increased to its maximum value at 80 K which is 45% compared to its room temperature value not enough to suggest splitting.
