Magnetic and Microwave Absorption Characteristics of Ti2+-Mn4+ Substituted Barium Hexaferrite

High-performance microwave absorption by optimizing hydrothermal synthesis of BaFe12O19@MnO2 core–shell composites

“…The reason for this is that Mn 4+ has a relatively smaller atomic radius in comparison to Fe 3+ . 41 …”

Physical and Microwave Absorption Characteristics of High Powered Ultrasonically Irradiated Crystalline BaFe9Mn1.5Ti1.5O19 Particles

“…However, its high coercivity must be reduced to some extent to facilitate the interaction between the magnetic field of electromagnetic waves and the magnetization of BHF. The reduced coercivity of Mn-Ti-substituted BHF was shown to increase microwave absorption (Manaf et al, 2017). Studies have shown that BaFe12-yMnyTiyO19 (y = 0.0; 0.5; 1.0; 1.5) with y = 1.5 was the best absorption up to a 40 dB reflection loss in 1-5 GHz (Priyono and Manaf, 2009).…”

“…Studies have shown that BaFe12-yMnyTiyO19 (y = 0.0; 0.5; 1.0; 1.5) with y = 1.5 was the best absorption up to a 40 dB reflection loss in 1-5 GHz (Priyono and Manaf, 2009). BHF as an electromagnetic wave absorber is widely used in many applications like information, communication using electronics components, and radar-absorbing material (Priyono and Manaf, 2009;Adi et al, 2017;Fitriana et al, 2017;Manaf et al, 2017).…”
