摘要：
Magnetic relaxation experiments were performed on gamma-Fe2O3 nanoparticle assemblies with interparticle interactions of varying strength. Weak waiting-time effects have been detected in an interacting-particle sample. The direct determination of the volume distribution from M-RE measurements and the application of our model for interparticle interactions are discussed. (C) 1999 Elsevier Science B.V.
