Temperature Variation of Magnetic Aftereffect



Lawrence H. Bennett


celerated testing of recording media to try to determine their life expectancy is one of the accepted tests that are currently utilized. The technique applied a reverse field to a magnetized decay and thus the amount of accelertion occurs at the peak of the irreversible susceptibility. The Preisach-Arrhenius model was proposed in attempt to answer the question of what the ratio of the decay rate is when vary considerably from sample to sample. An analysis of this model showed that it was able to explain the behavior magnetization decay at room temperature. However, the model predicted the decay rate should be essentially linear with temperature if other material parameters were constant and increase monotonically for real materials.
