Special Issue Information

Dear Colleagues,

The Special Issue aims to showcase the latest research and developments in the field of nanomagnetism. This multidisciplinary field encompasses the synthesis, characterization, and utilization of magnetic nanoparticles with diverse applications spanning medicine, electronics, energy, and more. The Special Issue will provide a platform for researchers to share their cutting-edge work, foster collaborations, and promote further advancements in this exciting area of study.

In recent years, the field of nanomagnetism has witnessed remarkable progress, driven by advances in materials science, nanotechnology, and characterization techniques. Magnetic nanoparticles, with their unique properties at the nanoscale, have garnered significant attention due to their potential for revolutionizing various fields. These nanoparticles exhibit magnetic behavior that differs from their bulk counterparts, enabling them to exhibit enhanced magnetic properties, tunability, and diverse functionalities. They offer immense potential for applications such as targeted drug delivery, magnetic data storage, biosensors, catalysis, and spintronics.

This Special Issue will encompass a wide range of topics, including innovative synthesis methods, cutting-edge characterization techniques, and emerging applications of magnetic nanoparticles. We welcome various types of contributions, including original research articles, insightful review articles, and forward-thinking perspective pieces. This Special Issue intends to foster collaboration and knowledge exchange among researchers working in different disciplines to further propel the field of nanomagnetism and unlock its tremendous potential in various scientific and technological domains.

The iron nitride materials, especially α″-Fe16N2, are considered one of the most promising candidates for future rare-earth-free magnets. However, the mass production of α″-Fe16N2 powders as a raw material for permanent magnets is still challenging. In this work, starting from iron lumps as a raw material, we have managed to prepare the α″-Fe16N2 powders via the gas atomization method, followed by subsequent nitriding in an ammonia–hydrogen gas mixture stream. The particle size was controlled by changing the gas atomization preparation conditions. X-ray diffractograms (XRD) analyses show that the prepared powders are composed of α″-Fe16N2 and α-Fe phases. The α″-Fe16N2 volume ratio increases with decreasing powder size and increasing nitriding time, reaching a maximum of 57% α″-Fe16N2 phase in powders with size below 32 ± 3 μm after 96 h nitridation. The saturation magnetization reaches the value of 237 emu/g and a reasonable coercivity value of 884 Oe. Compared to the saturation magnetization values of α-Fe powders, the α″-Fe16N2 powders prepared through our proposed approach show an increase of up to 10% in saturation and demonstrate the possibility of mass production of α″-Fe16N2 powders as precursors of permanent magnets without rare earths.
