Abstract
In this study, the enhancement of magnetic properties in Fe2O3 nanoparticles through nanostructural modification via carbon coating is investigated. Fe2O3 and carbon‐coated Fe2O3 nanoparticles are synthesized using the solvothermal method. Structural, morphological, optical, and magnetic properties are comprehensively analyzed. The results demonstrate a significant reduction in particle size upon carbon coating, effectively mitigating agglomeration. Furthermore, carbon‐coated nanoparticles exhibit substantial enhancement in coercivity, remanence, and saturation magnetization suggesting improved magnetic behavior in comparison to their uncoated counterparts. This enhancement is attributed to the prevention of spin misalignment at the nanoparticle surface by the carbon coating, as well as the formation of distinct magnetic domains due to the reduced particle size. The observed improvements underscore the effectiveness of carbon coating in tailoring the magnetic properties of Fe2O3 nanoparticles for applications in magnetic devices and biomedical systems, such as magnetic hyperthermia and drug delivery systems, where precise control over magnetic behavior is crucial.
期刊介绍:
Physica status solidi (RRL) - Rapid Research Letters was designed to offer extremely fast publication times and is currently one of the fastest double peer-reviewed publication media in solid state and materials physics. Average times are 11 days from submission to first editorial decision, and 12 days from acceptance to online publication. It communicates important findings with a high degree of novelty and need for express publication, as well as other results of immediate interest to the solid-state physics and materials science community. Published Letters require approval by at least two independent reviewers.
The journal covers topics such as preparation, structure and simulation of advanced materials, theoretical and experimental investigations of the atomistic and electronic structure, optical, magnetic, superconducting, ferroelectric and other properties of solids, nanostructures and low-dimensional systems as well as device applications. Rapid Research Letters particularly invites papers from interdisciplinary and emerging new areas of research.
