Blocking Temperature and Hysteresis Characteristics of Nanoparticles of Oxidated Magnetite

Nature inspired synthesis of magnetite nanoparticle aggregates from natural berthierine

“…The magnetization in agglomerated magnetite is more sensitive to temperature than the smaller individual dispersed particles. [16][17][18] The present study, therefore, investigates the natural MNAs and compares their characteristics with reference magnetite and synthesized MNAs through laboratory experiments. The results underline the use of MNAs as a potential indicator of geological environment in which the iron ore was deposited and, provide a possible nature inspired methodology for preparation of MNAs for societal use.…”
