dc.description.abstractHigh-entropy oxides (HEOs) are considered promising materials in many electrical applications, especially in the fields of batteries, energy storage and conversion, and catalysis. The study material, (CoCrFeNiMn)3O4 in particular, has been shown to possess gigantic capacitance, a characteristic that emanates from its oxide precursors properties. The material was successfully prepared using the solid-state reaction method, as the material showed structural stability despite its different composition and the possibility of controlling its magnetic properties based on its composition, as the saturation value of Fe excessive addition-S2.Fe reached 52 emu/g, with it having a relatively high coercivity value, which is estimated at 1102.47 Oe. It was also observed that electron hopping between different oxidation states is based on the high-resolution X-ray photoelectron spectroscopy (XPS) results, which has a role in the magnetic properties.en
