Abstract

The properties of Fe ions in the $ CdFe_2$$O_4$ and $CdFeAlO_4$ were investigated using the Mossbauer spectroscopy, in the temperature range from 300K to 900K. The calculated Debye temperature, recoil free fraction, mean square displacement and velocity are, 476.5K, 0.835, 3.39$\times$10\ulcorner$\textrm{cm}^2$, and 1.11$\times$10\ulcorner$\textrm{cm}^2$sec$^2$for Fe ions in the $CdFe_2$$O_4$ and 369.0K, 0.741, 5.65$\times$10\ulcorner$\textrm{cm}^2$ and 1.33$\times$10\ulcorner$\textrm{cm}^2$/$sec^2$in the $CeFeAlO_4$. The difference of the properties in the two samples were explained by the variation of the Fe\ulcorner-O\ulcorner bonding length with the substituted Al ions.
