Coercivity approaching theoretical limit
Suppression of surface defects significantly enhances coercivity of M-type ferrite particles without altering the intrinsic magnetization reversal mode, providing a new basis for preparing high-coercivity permanent magnet nanoparticles.

Even without surface defects, coercivity remains below theoretical value and decreases with increasing particle size
Surface defects further reduce coercivity and magnetic hardening effect
