The dynamical behavior of g-Fe 2 O 3 particles dispersed in a polymer have been investigated by a.c. susceptibility and Mo ¨ssbauer spectroscopy measurements. The effect of interparticle interactions on the relaxation time is satisfactorily described by a superparamagnetic model where the dipolar en
The -Fe 2 O 3 particles with nanometer size have been hydrothermally synthesized using 2-methoxyethanol (MOE)-H 2 O mixed solvent and acetylacetone(Hacac) as additive from iron(II) 2-methoxyethoxides (Fe(MOEO) 2 ). The typical reaction conditions are as follows: reaction temperature 140°C reaction t
