    The initial mixture of magnetite with 20 vol.% of cerium carbonate is treated at 673 K and 1173 K leading
    to formation of Fe-oxide/cerium dioxide reactive sorbents. The main interest is devoted to iron-oxide composition and interactions between both oxides mainly influencing the structural and physical magnetic properties. While the morphology did not change markedly, the transformations of initial magnetite into maghemite and/or hematite contributed to changes in magnetic properties measured at 2 K and 300 K. The magnetization curves were analysed using a theoretical Jiles–Atherton approach and discussed in connection with sorbents microstructure.
