Abstract
) and reduced eddy current loss promoted multi-mechanistic energy dissipation. These findings demonstrate that Co-Al co-substitution effectively tailors lattice strain, anisotropy, and interfacial polarization, providing a rational design strategy for high-efficiency microwave absorbers and EMI-shielding hexaferrites in the X-band region.
