Electromagnetic Properties of Substituted Barium Hexaferrites

Acta Physica Polonica A, 2008
Substituted M-type ferrite BaFe12−2x(Me1Me2)xO19, 0 ≤ x ≤ 0.6 was prepared by both mechanical alloying and precursor method, where Me1 = Co, Ni, Zn, Sn and Me2 =Ru, Ti, Zr, Sn. Magnetic phase purity, change of saturation polarization, Curie temperature, coercivity and magnetic susceptibility was studied as function of x.

Broadband and Wide‐Angle Nonreciprocal Electromagnetic Transport via Gradient Permeability‐Near‐Zero Metastructures

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
ABSTRACT Breaking time‐reversal symmetry to achieve broadband and wide‐angle nonreciprocity is critical in electromagnetic waves manipulation. While Epsilon‐Near‐Zero materials have revolutionized the control of Transverse Magnetic modes, realizing comparable broadband nonreciprocity for Transverse Electric (TE) modes remains a formidable challenge ...

Magnetic and dipole moments in indium doped barium hexaferrites [PDF]

Journal of Magnetism and Magnetic Materials, 2018
Abstract Crystal and magnetic structure of the doped BaFe12−xInxO19 samples were refined by the results of investigations using high resolution neutron powder diffraction and vibration sample magnetometry at different temperatures. The refinements were realized in frame of two space groups.

High‐Performance X‐Band Electromagnetic Interference Shielding in Flexible Barium Hexaferrite/Cobalt‐Based Microwires/Silicone Rubber Ternary Composites via Magnetic–Conductive Synergy

Advanced Electronic Materials, Volume 12, Issue 10, 25 May 2026.
A flexible ternary composite combining barium hexaferrite (BHF), Co–Microwires, and silicone rubber exploits magnetic–conductive synergy to deliver tunable X‐band EMI shielding, reaching a 16.9 dB at 9.8 GHz (surpassing the 10 dB industrial benchmark). Shielding behavior shifts between reflection and absorption with BHF loading and Co–Microwires counts
