Abstract Investigation by Mössbauer spectroscopy of non-aggregated nanometric γ-Fe2O3 particles dispersed in polymer is reported. Magnetic interactions between the particles were controlled by varying the particle concentration in the polymer. The results show that over the investigated range, the interactions make the relaxation time shorter. Infield experiments show spin canting which increases with decreasing particle size.
