Figure 4: a) H||(110) (hard axis) loop for a Fe131Å/Ag55Å/Fe124Å/Ag28Å sandwich. Both Fe films have a (100) easy axis.

a Fe131Å/Ag55Å/Fe124Å/Ag28Å sandwich.
Both Fe films have a (100) easy axis.
b) H perpendicular to I||(110) magnetoresistance of the same
sandwich. Note the second peak in the magnetoresistance,
which does not correlate with any discontinuity in the
magnetization curve. This second peak is believed to
correspond to the reversal of a component of the
magnetization which is orthogonal to the applied field, and
thus not directly observable by the magnetometer. Dashed and
solid lines are as in Fig. 2.
