Square-plated magnetite nanocrystals with a high aspect ratio (~ 1/9) are prepared by the co-precipitation from a solution in the presence of arabinogalactan. The magnetic anisotropy constant of particles is several times higher than the constant of spherical magnetite particles, which leads to increased hysteresis properties for specific volume of the particle.
