Chemical solution deposition in the presence of arabinogalactan makes it possible to prepare magnetite nanocrystals in the form of square plates with a high aspect ratio (similar to 1/9). The magnetic anisotropy constant of particles is several times higher than that of spherical magnetite particles, which enhances the hysteretic properties with a small particle volume retained.
