Fig. 3
Temperature dependence of (a-b) shift field (HEB)and c-d) coercivity (HC) of magnetic hysteresis loops, with the TB marked by dashed lines. Results are determined from LMOKE data for a field cooled sample for (a, c) 50 Å Fe step and (b, d) 120 Å Fe areas. Data acquired for (a, c) H || Fe[\(1\overline{1 }0\)] and (b, d) H || Fe[001], LMOKE geometries. CoO thickness dependence of (e) critical temperatures and (f) HEB at 80 K.
