Temperature dependence of the time decay of the magnetization in particulate media
Abstract
The time decay of magnetization in commercial CrO2, gamma-Fe2O3, and Co-doped gamma-Fe2O3 tapes is investigated experimentally at temperatures 6, 50, 100, 200, 250, and 300 K. The decay is found to be linearly dependent on temperature in all four tapes tested, but when the curves are extrapolated to 0 K, there is a large finite intercept - in contrast to similar measurements on ferromagnetic materials and rocks.
