Abstract
In addition to classical body domain patterns, a profusion of complex maze like domain structures have been observed using the Bitter technique on titanomagnetites. Controversy persists over how important a role such complicated domain patterns play in remanent magnetization. We have compared the magnetic properties of single particles, which exhibit complex patterns with those that exhibit simple ones. IRM acquisition and DC and AF demagnetization of IRMs of single particles were measured. We found that both types of grains exhibit similar bulk magnetic properties. The simple patterns reorganize with changing magnetization state while complicated patterns apparently remain constant. We suggest that the remanent magnetization of grains with complicated patterns is carried by the bulk of the particle within which a more simple domain structure controls magnetic behavior.This publication has 7 references indexed in Scilit:
