Examples of stepwise a, d alternating field demagnetization (AFD); b, e thermal demagnetization (ThD); and c, f progressive AFD after ThD at 300 °C. The filled and open circles correspond to projections onto the horizontal and vertical planes, respectively. The data points that likely indicate secondary components are shown in gray in (f)
