The influence of stress path on thermoremanent magnetization (TRM) was studied experimentally. Specimens with a TRM were cyclically loaded under three different conditions: hydrostatic pressure, uniaxial compression, or uniaxial strain. Initial loading resulted in a large decrease in magnetization at stress and permanent demagnetization at the termination of the stress cycle. The observed magnetic changes were much larger for non-hydrostatic loading than for hydrostatic compression. With subsequent loading to the same peak stress over the same path, stress induced variations in magnetization were smaller and tended to become reproducible; shear stress produced greater magnetic perturbations. ¿ American Geophysical Union 1988
