REPTATION EFFECTS IN PARTICULATE SYSTEMS .1. THEORETICAL PREDICTIONS

In this paper we derive a theory which describes the effects of field cycles on the magnetization in particulate systems, i.e., the reptatio n effects. This theory predicts that the difference between reptation and time-dependence measurements arises from time dependence which occ urs during the cycling of the magnetic field, i.e., during the field s weep. These predictions are found to be in good agreement with experim ental data published in the following article [Lewis et al. (these pro ceedings)].
