FIG. 1.

(Color online) Geometry of the AMR experimental setup with the relative orientation of the bias, DC current, external magnetic field, H ext, and the various switching fields between different Fe easy axes.

Image of FIG. 2.
FIG. 2.

(Color online) Angle-dependent R(H) signals at (a) φ = −30°, and (b) φ = −90° at 10 K; and at (c) φ = −30°, and (d) φ = −90° at 300 K. The orientations of the Fe spins in the switching processes are represented by the arrows enclosed in a square.

Image of FIG. 3.
FIG. 3.

(Color online) Angular dependence of the experimentally observed switching fields (symbols) and the corresponding theoretical fitting results (curves) at (a) 10 K, and (b) 300 K. The switching fields, represented by different symbols and curves, correspond to the magnetic transitions between the different initial and final Fe easy axes orientations.

FIG. 4.

(Color online) Temperature dependence of the parameters, ɛ90°/M, K eb/M, and K u/M, given by the fitting for the angular dependent switching fields. Linear lines are guides to eye.
