Figure 4: Spin-orientation-dependent Néel temperature by MOKE measurements.
From: Antiferromagnetic proximity effect in epitaxial CoO/NiO/MgO(001) systems
Typical hysteresis loops for the systems (a) Fe/CoO/MgO(001) and (b,c) Fe/CoO/NiO/MgO(001) with indicated layer thicknesses at different temperatures. (d) Temperature-dependent Hc of Fe/CoO/NiO/MgO(001) with different NiO thickness. Inset shows an enlargement of the Hc around TN. Arrows denote the CoO TN evaluated from the discontinuity of the slopes of the Hc(T) curves. (e) CoO TN as a function of NiO thickness for the Fe/CoO/NiO(wedge)/MgO(001) sample. Inset in (e) shows the structure of the sample.
