Abstract

The paper addresses the physical mechanism of the magnetization self-reversal in rocks. The self-reversal is the phenomenon of magnetization of a rock in the direction antiparallel to the magnetizing field. Experimental data on the self-reversal of thermal and thermoremanent magnetizations in natural analogues of hemoilmenites and synthetic hemoilmenites are presented. It is shown that the most probable mechanism of self-reversal is the single-phase Néel mechanism of the N-type. The N-type mechanism underlies the physical mechanism and numerical model of self-reversal developed in the paper. The numerical modeling results are compared with experimental data.
