摘要
The dynamical properties of a series of gamma-Fe2O3 nanoparticles (mean diameter: 7.1 nm) samples, with different aggregation states, have been studied by measuring the time decay of the thermoremanent magnetization at different temperatures. The effects of interparticle interactions on the temperature dependence of the relaxation rate are discussed. The results are in agreement with the proposed model.
