Magnetic properties of magnetite strongly depend on such factors as the NP size, shape, and chemical phase. Bulk magnetite can be described as ferrimagnetic as a result of the parallel alignment of magnetic moments of the tetrahedral site and antiparallel alignment of the Fe 2+ and Fe 3+ spins of octahedral sites. However, when the particle size is decreasing the tendency to spontaneous magnetization becomes weaker and magnetite …
