Enhanced magnetic anisotropy in structure, static, and dynamic magnetic properties for Ba3−xLaxCo2Fe24O41 hexaferrites
Co2Z is a planar ferrite, particularly suitable for soft magnetic applications. There is currently a lack of in-depth research on its high-frequency properties. La3+ ion is a potential ion to regulate its magnetism. Based on this, the crystal structure, microstructure, static, and dynamic magnetic properties of Ba3−xLaxCo2Fe24O41 (x = 0.0, 0.05, 0.1, 0.15, 0.2, and 0.25) ceramics were investigated. The findings demonstrate that La substitution retains the crystal structure and form, yet the introduction of extra charge leads to the formation of Fe2+ ions, resulting in a slight decrease in magnetic moment from 51.9 to 48.9 emu/g, while a notable increase in the out-of-plane anisotropic field from 12.2 to 18.3 kOe, which significantly impacts the high-frequency complex magnetic permeability spectrum. Additionally, a thorough analysis of the high-frequency magnetic spectrum indicates that both domain wall movement and magnetization rotation contribute to the magnetic permeability, with magnetization rotation playing predominant. Particularly exciting is that the high-frequency magnetic spectrum results show that the substitution of La for Ba considerably raises the resonance frequency from 2.41 to 3.30 GHz that can be attributed to the increased anisotropy. In conclusion, the substitution of La markedly enhances the high-frequency magnetic properties of Co2Z.
期刊介绍:
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
