Figure F11. Thermal demagnetization results (Sample 324-U1347A-17R-2, 94–96 cm). A. Equal angle spherical projection. B. Zijderveld plot. C. Magnetic intensity vs. demagnetization step. This sample shows an example of a small self-reversal at moderate heating steps. Note that demagnetized magnetization directions are consistent through the self-reversed section except at 550°C.
