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

Room-Temperature Multiferroic Liquids: Ferroelectric and Ferromagnetic Order in a Hybrid Nanoparticle-Liquid Crystal System. [PDF]

Adv Mater
A hybrid fluid combining ferrimagnetic nanoplatelets and a ferroelectric nematic displays coexisting magnetization and polarisation at room temperature. This self‐assembled multiferroic shows strong magnetoelectric effect and nonlinear optical response, offering a soft, reconfigurable platform for next‐generation sensing, actuation, and photonic ...

Aluminum Doping and Nanostructuring Enabled Designing of Magnetically Recoverable Hexaferrite Catalysts

ACS Omega, 2022
We demonstrate an approach based on substituting a magnetic cation with a carefully chosen isovalent non-magnetic cation to derive catalytic activity from otherwise catalytically inactive magnetic materials. Using the model system considered, the results
