Description
The irradiation damage created by the high energy heavy ions of GANIL in two ferrimagnetic oxides (BaFe12O19 and Y3Fe5O12) have been observed by Moessbauer spectroscopy. The Moessbauer spectra confirmed the paramagnetic state of the amorphous phase observed by electron microscopy. In the low energy range (E<0.9 GeV), a smooth transition to a frustrated magnetic order has been observed by decreasing the temperature down to 4.2 K. In the high energy range (E>0.9 GeV), the contribution of electronic process could explain the rate of amorphization of Y3Fe5O12
