AI Article Synopsis
- Soft phase magnetic Fe-B nanoparticles were created using a coprecipitation method, and hard phase Nd-Fe-B nanoparticles were produced through mechanical ball milling of bulk Nd-Fe-B.
- An exchange-coupled nanocomposite magnet was formed by combining Nd-Fe-B and Fe-B nanoparticles and further processing them with a mechanical ball mill.
- The final product was annealed in an electronic furnace under hydrogen, resulting in good magnetic properties, indicated by a smooth hysteresis loop and a high remanence ratio (Mr/Ms > 0.5).
Article Abstract
Soft phase magnetic Fe-B nanoparticles were prepared by coprecipitation and the hard phase magnetic Nd-Fe-B nanoparticles were obtained from mechanical ball mill of the bulk Nd-Fe-B with a shaker mill. Also mechanical ball mill technique was applied to the mixture of Nd-Fe-B and Fe-B nanoparticles to build up an exchange-coupled nanocomposite magnet. It was loaded in electronic furnace and annealed under a flow of hydrogen at 953 K for 30 min. The exchange coupled interaction of isotropic magnets was characterized by smooth hysteresis loop with a high value of remanence (Mr/Ms > 0.5).
