Non-equilibrium dynamics in an interacting nanoparticle system
arXiv:cond-mat/9909123 · doi:10.1103/PhysRevB.61.1261
Abstract
Non-equilibrium dynamics in an interacting Fe-C nanoparticle sample, exhibiting a low temperature spin glass like phase, has been studied by low frequency ac-susceptibility and magnetic relaxation experiments. The non-equilibrium behavior shows characteristic spin glass features, but some qualitative differences exist. The nature of these differences is discussed.
