🔥 Effect of Annealing Temperature on Magnetic Phase Transition in Fe₃O₄ Nanoparticles 🧲 Introduction Fe₃O₄ (magnetite) nanoparticles are widely studied due to their unique magnetic properties, biocompatibility, and technological applications. One of their most fascinating features is the magnetic phase transition, which can be strongly influenced by annealing temperature. Annealing alters crystal structure, particle size, and magnetic ordering. This transition is closely related to the famous Verwey transition , discovered by Evert Verwey , where magnetite undergoes a change in electrical and magnetic behavior. 🌡️ What is Annealing and Why is it Important? Annealing is a heat treatment process that improves material properties by: 🔹 Increasing crystallinity 🔹 Reducing defects 🔹 Improving atomic ordering 🔹 Enhancing magnetic alignment In Fe₃O₄ nanoparticles, annealing temperature plays a critical role in determining magnetic phase stability.
