Special Issue Information

Dear Colleagues,

The study of magnetic materials and devices at the nanoscale has become one of the most interesting and complex research fields, from both basic and applied perspectives. In recent decades, the fundamental understanding of static and dynamic magnetic processes at the nanoscale has greatly improved, owing to innovative experiments and theoretical approaches. We have seen rapid progress in the development of novel techniques for nanoscale magnetic characterization with ultrahigh spatial, temporal, and energetic resolutions. Notably, ultrafast laser technologies combined with X-ray- and electron-based pump–probe approaches have made fast strides and thus attracted considerable research interest. Therefore, a timely summary and collections of the current status of different technologies and their respective applications of nanoscale magnetic materials devices are highly valued.

This Special Issue focuses on the latest theoretical developments and practical applications of novel magnetic characterization techniques that have been successfully established and applied on various nanoscale magnetic materials and devices. We aim to attract both academic and industrial researchers in order to pool the current knowledge of nanoscale characterization of nanomagnetism and to present new ideas for future application and new technologies for advancing nanomagnetism research.

In the rapidly emerging field of biomedical applications, multifunctional nanoparticles, especially those containing magnetic and plasmonic components, have gained significant attention due to their combined properties. These hybrid systems, often composed of iron oxide and gold, provide both magnetic and optical functionalities and offer promising avenues for applications in multimodal bioimaging, hyperthermal therapies, and magnetically driven selective delivery. This paper focuses on the implementation of advanced characterization methods, comparing statistical analyses of individual multifunctional particle properties with macroscopic properties as a way of fine-tuning synthetic methodologies for their fabrication methods. Special emphasis is placed on the size-dependent properties, biocompatibility, and challenges that can arise from this versatile nanometric system. In order to ensure the quality and applicability of these particles, various novel methods for characterizing the magnetic gold particles, including the analysis of their morphology, optical response, and magnetic response, are also discussed, with the overall goal of optimizing the fabrication of this complex system and thus enhancing its potential as a preferred diagnostic agent.
