Abstract
The effect of high-energy ball milling (HEBM) on the cation distribution of manganese ferrite (MnFe
2O
4) was investigated by means of Mössbauer spectroscopy in the presence of high external magnetic field. The results show that the Fe
3+ ion occupancy to A site increases with increasing the milling time. Particle-size investigation shows that this increase of the inversion parameter could be attributed to a particle-size reduction in the ball-milled samples.
