Description
Hassan Ali, Samar Fatima, Tanvir Hussain, and Khawar Ismail compare, in 2026 work, two oxide nanopowders, spinel nickel ferrite and perovskite calcium manganite, for energy-related uses. Both families promise magnetic and electrical traits useful in storage and shielding devices. Powders made by the same gel route were baked across wide temperature ranges.
X-ray patterns confirmed both crystal structures, with best grain sizes near 25 nanometers for the ferrite and near 15 for the manganite. Computer calculations echoed the measured structures. Magnet testing showed the ferrite strongly magnetic, reaching 29.61 emu per gram at saturation. The manganite managed only 1.71 emu per gram by the same measure. The ferrite suits magnetic roles; the manganite leans dielectric.
