Enhanced microwave absorbing performance of Sr2+ substituted Nickel-Cobalt nano ferrite for radar and stealth applications

Effect of ferromagnetic cobalt on characteristics of coercive Aluminium substituted BaFe11.5Al0.5O19 hexaferrites

“…They possess good electrical and chemical stability, corrosion resistance and have hexagonal regularity [7]. These properties make M-type hexaferrites attractive in numerous magnetic devices, such as permanent magnets, micro-wave devices, and magnetic recording media [8][9][10]. They are crucial in the enterprise of micro-wave instruments (such as phase shifters, circulators, and filters), biomedical applications, and chemical sensing [11][12][13].…”

“…Various techniques are utilized to synthesize M-type hexaferrites, which consist of co-precipitation method, hydrothermal method, solgel method, reverse micelle method, standard ceramic process, and microwave-assisted synthesis [15][16][17]. The traditional ceramic process is mainly used for synthesizing hexaferrites and has many benefits compared to other techniques [9,18]. The hydrothermal method is also widely used to develop hexaferrites because it can produce high-quality M-type hexaferrites with narrow particle size distribution and good crystallinity [19,20].…”

High-Temperature, Lightweight Ceramics with Nano-Sized Ferrites for EMI Shielding: Synthesis, Characterisation, and Potential Applications

“…CoF 2 O 4 can be synthesised via the sol-gel method with subsequent auto combustion [23], reverse coprecipitation [24], and direct and hydrothermal synthesis [25]. CoF 2 O 4 has broad applications in various fields [26], from their use as antimicrobial components, in which superparamagnetic cobalt ferrite NPs are used against several kinds of pathogenic microorganisms [27], to the design of EMI shielding materials [28][29][30]. Therefore, using CoFe 2 O 4 nanoparticles (NPs) in composite production could have a positive effect.…”
