摘要: γ-Fe2O3 nanocrystals with a mean radius of 4.2 nm have been synthesized in polymer matrix by an ion exchange and precipitation reaction. Magnetization susceptibility data from experiment computer simulations indicate that the system is superparamagnetic. The optical absorption edge red shifted respect to epitaxially-grown single-crystal film γ-Fe2O3. shift attributed lattice strain small particles.
