Spinel ferrites are attractive for high frequency applications due to their larger direct current (dc) resistivity and low dielectric loss. In the present work, Co0.6Zn0.4HoxFe2-xO4 (x = 0.00 and 0.1) spinel ferrites were prepared by sol-gel method. The X-ray diffraction pattern showed that both samples had cubic spinel structure, while in sample (x = 0.1), the secondary phase (HoFeO3) was also observed. The dc resistivity was increased with the addition of holmium ions. As the temperature increased, the dc resistivity was decreased by proving their semiconducting nature. The dielectric properties were also measured as a function of temperature and frequency. The sample which was composed by the substitution of holmium ions contained low value of dielectric loss. The magnetic properties were also experimentally measured by applying the field up to 2000 oersted. The small area covered by hysteresis loop proved that both samples possessed soft nature of magnetic materials.

Magnesium‐alloy (Mg‐alloy) materials have attracted considerable attention recently due to their potential applications in electromagnetic interference (EMI) shielding. EMI shielding is a technique to prevent unwanted electromagnetic fields from interfering with the regular operation of electronic devices and systems. EMI shielding is essential for electronics, communication, computers, aerospace, and defence, where high performance and reliability are required. A material’s EMI shielding effectiveness (SE) depends on several factors: its conductivity, magnetic permeability, reflectivity, absorption, and multiple scattering. Mg‐alloys have several advantages over other conventional shielding materials, such as Al‐alloys. These alloys have a lower density, higher specific strength and stiffness, and a higher damping capacity. Mg‐alloys also have high conductivity and magnetic permeability, which can enhance the SE of the material. Moreover, through various methods, such as alloying, heat treatment, surface treatment, and composite fabrication, Mg alloys can be modified to improve their SE and other properties. This review summarizes the recent progress and challenges in developing Mg‐alloy materials for EMI shielding applications. We discuss the effects of different factors on Mg‐alloys’ SE, such as composition, microstructure, frequency, and thickness. Also, we discuss the importance of Mg‐Li alloys and why they are better electromagnetic shielding materials than conventional Mg alloys. Finally, we provide some perspectives and suggestions for future research directions.This article is protected by copyright. All rights reserved.

“…As one important wave band in the electromagnetic wave, X-Band electromagnetic waves are the most common used in military and telecommunications devices. [5][6][7][8] Obviously, electromagnetic interference (EMI) is a great challenge in the application of the certain high-end precision scientific and military equipment. For the reflectional EMI shielding materials, EMI shielding is mainly based on electromagnetic wave reflection by charge carriers.…”
