The $\mathrm{Li_{0,7}Na_{0,3}FeGe_{2}O_{6}}$ solid solution has been synthesized by the solid-phase reaction. The clinopyroxene compound has been investigated by X-ray diffraction and by bulk magnetic measurements. The structural properties of the cation substitution compound are presented. Using SQUID techniques the temperature dependence of the magnetic susceptibility was measured. It exhibits a sharp maximum, which is suggested the phase transition from the paramagnetic state to a magnetically ordered state below 15.5 K in the sample of pyroxene solid solution.
Keywords: pyroxene, crystal structure, magnetic properties.
Mots-clés : solid solution
