Fig. 2
LMOKE measurements of CoO(111)/Fe(110) magnetic hysteresis loops, for 30 Å thick CoO overlayer, for different Fe thicknesses. Room temperature (a–d) and 80 K (e–l) measurements are shown for two in-plane orientations of external magnetic field, namely H || [\(1\overline{1 }0\)] and H || [001]. All FC loops (e–h) correspond to measurements after FC procedure in negative field along the same orientation as external magnetic field used for subsequent particular measurement. The ZFC loops (i–l) correspond to cooling without the external magnetic field after magnetizing the Fe layer using negative field along the particular measurement axis.
