(a) Out-of-plane hysteresis loops showing the major (solid line) and minor (symbols) loop scans for the 20-nm sample. The first transition of the full loop scan arises when magnetization switches in one of GaMnAsP layers, causing an antiparallel magnetization configuration of the system. Curved arrows indicate the direction of minor loop scan. Insets show the schematic diagrams for the magnetization configurations at the corresponding positions. (b) Out-of-plane “Up” and “Down” minor loops are plotted together to find the value of the minor loop shift by calculating the average between (Hu1 − Hd1) and (Hd2 − Hu2).
