FIG. 5.

Magnetization isotherms of the six samples studied measured at . (a) layers, (b) bilayers, and (c) bilayers. Filled symbols are used for samples with thick and empty symbols depict those with the thick . The insets illustrate the low magnetization regime.

FIG. 6.

The first quadrant of the normalized magnetization isotherms at of the six samples studied. Samples with thick layers are represented by filled symbols, whereas empty symbols are used for the specimens with thick layers. Measurements are performed up to but we only display the magnetic field range for the sake of clarity.

TEM dark field micrographs of plane view specimens of (a) , (b) , and (c) . The images have been obtained selecting a (440)-type reflection of .

Tables

Generic image for table
Table I.

Summary of the experimental thickness of the different ferromagnetic layers, magnetization per area unit, and volume magnetization of all the samples studied as well as of a thick Fe test sample grown on MgO (001). Calculated values of magnetization for Fe and extracted from experimental data are included.
