Special Issue Information

Dear Colleagues,​

Magnetic nanomaterials, defined by size-dependent magnetic properties, have evolved from early observations of nanoscale magnetism to today’s precision-engineered materials. Milestones include the discovery of superparamagnetism in the 1970s, breakthroughs in controlled synthesis in the 1990s, and the rise in interdisciplinary applications in the 21st century, laying the foundation for current research.​​

This Special Issue aims to showcase cutting-edge advancements in magnetic nanomaterials, fostering academic exchange and bridging fundamental research with practical applications. It covers properties (magnetic, optical, electronic), synthesis (bottom-up/top-down strategies, green methods), and diverse applications across fields.​

Recent progress highlights precise structure–property regulation, innovative synthesis techniques (e.g., template-assisted, laser-induced methods), and emerging applications in spintronics, targeted therapy, environmental remediation, and quantum information science.​

We welcome original research, reviews, and communications focused on basic magnetic properties at the nanoscale; novel synthesis and modification strategies; advanced characterization techniques; and practical applications. Submissions should emphasize innovation, scientific rigor, and potential impact.

As a ferrite material with excellent magnetic and dielectric properties, CoFe2O4 is in high demand for applications in areas such as wave absorption and magnetic storage. Effective regulation of its nanoscale morphology is central to improving application performance. Conventional synthesis methods often face challenges including poor particle dispersion and irregular morphology, which limit further optimization of material properties. In this study, a combined approach of microwave hydrothermal synthesis and annealing was employed to systematically investigate the effects of hydrothermal temperature, reaction time, and annealing parameters on the morphology and properties of CoFe2O4. The samples were characterized using X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, and other techniques. Experimental results show that process parameters exert a notable influence on the crystallinity, particle dispersibility, magnetic and wave-absorbing properties of CoFe2O4: the sample prepared by microwave hydrothermal treatment at 75 °C for 30 min exhibits relatively better wave-absorbing performance, with a minimum reflection loss of less than −30 dB and an effective absorption bandwidth covering 8~16 GHz; the sample treated at 100 °C for 15 min shows a more balanced magnetic performance, with the saturation magnetization approaching 60 emu/g. The quantitative structure–property relationships of pure-phase CoFe2O4 across microwave hydrothermal and post-annealing processes, and achieve stable, reproducible performance enhancements under optimized mild conditions. These results supplement key experimental data for the low-temperature preparation of CoFe2O4 and establish a practical, energy-efficient parameter framework for future structural design and process optimization of this important magnetic material.
