“…Also, it is noted that the highest reminence ratio is obtained for sample B and the lowest coercive field for sample A. This is due to the stoichiometry of Mn containing spinel ferrites which has a strong effect on the shape of the hysterics loop, where the squareness ratio is larger at higher concentration of anion vacancies [28].…”

Nano-particles polycrystalline Mn 0.45 Ce x Fe 2.55-x O 4 ; x = 0.0 and 0.1 were synthesized using the co-precipitation method and subsequently heat-treated. In each heat treatment the prepared samples have been investigated by XRD and TEM. The electric and magnetic properties for each heat treatment have been studied to produce samples with distinguishable character that can be suitably used in different technological applications. The obtained hysteresis loop of all the investigated samples belong to the Isoperm loop. The Mn 0.45 Ce 0.1 Fe 2.45 O 4 samples with particle size (9.9 nm) are characterized by the lowest coercive field (28.87Oe) and highest T C (582 K), they can be used in medical applications. The samples Mn 0.45 Fe 2.55 O 4 (45 nm) after two steps of heating treatment shows a paramagnetic behavior and have the highest remenance ratio (0.236) and a very low dielectric loss (0.07). They can thus be used as memory storage and in several microwave applications. Mn 0.45 Fe 2.55 O 4 (50 nm) after three steps of heating treatment has the highest dielectric constant (1500), the lowest resistivity and lowest activation energy (0.38 eV), which are the suitable properties needed for the electronic devices.
