Microstructure Parameters-Dependent Non-Collinear Magnetic Structure in Scandium-Doped M-Type Hexaferrite Nanocrystal

The selective occupancy of Sc 3+ ions at the different Fe 3+ sites within the M-type ferrite weakens the super-exchange interaction between Fe1, Fe2, and Fe5 ions, which disrupts interactions between different blocks and stabilizes the conical state.
