W-Type Hexaferrite Film-Enabled Magnetic Resonance Engineering for Tailored Upper Stop-Band Suppression in Millimeter-Wave Bandpass Filters [PDF]

Micromachines
In this study, we propose a novel approach to enhance upper stop-band attenuation in a split-ring resonator-based bandpass filter by partially inserting W-type hexaferrite films into a strategically placed mechanical hole.

Review on Y-type hexaferrite: Synthesis, characterization and properties

Applied Surface Science Advances, 2023
Ferromagnetic properties of hexaferrites induce magnetisation inside their crystal structure, separating them into uniaxial and ferroxplana hexaferrites. Y-type is the first observed ferroxplana ferrite with spontaneous magnetization in the basal c-plane

Thin Films of BaM Hexaferrite with an Inclined Orientation of the Easy Magnetization Axis: Crystal Structure and Magnetic Properties [PDF]

Nanomaterials
Thin (~50 nm thick) BaM hexaferrite (BaFe12O19) films were grown on (1–102) and (0001) cut α-Al2O3 (sapphire) substrates via laser molecular beam epitaxy using a one- or two-stage growth protocol. The advantages of a two-stage protocol are shown.

Preparation of strontium hexaferrite magnets from celestite and blue dust by mechanochemical route [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2008
In the present investigation celestite (natural ore of strontium) and blue dust (iron ore fines) have been used for the preparation of strontium hexaferrite powder. The mechanical alloying process has been adopted to prepare strontium hexaferrite powder.
