FIG. 1.

XRD measurements, (a) scan and (b) in-plane −scan, of the sample with . (c) Geometry of the field cooling direction, magnetic anisotropies, and the external magnetic field. (d) Definition of the various switching fields between different Fe easy axes.

FIG. 2.

Typical longitudinal and transverse MOKE loops measured at various field orientations for three samples with different . Results for 4 nm sample at (a) (square loop), (b) (double-side two-step loop, opposite semicircles), and (c) (double-side two-step loop, opposite semicircles). Results for 5 nm sample at (d) , (e) (asymmetrically shaped loop), and (f) (double-side two-step loop, same semicircle). Results for 6 nm sample at (g) , (h) (double-side two-step loop, same semicircle), and (i) (double-side two-step loop, same semicircle). The orientation of Fe spins in the switching processes is represented by the arrows enclosed in a square.

FIG. 3.

Typical field orientation dependence of the experimentally observed switching fields (symbols) and the corresponding theoretical fitting results (curves) for Fe/IrMn bilayers with (a) , (b) , and (c) . The switching fields, represented by different symbols and curves, correspond to the magnetic transitions between different initial and final Fe easy axes orientations. (d) The effective anisotropy fields derived by the above fittings for Fe/IrMn bilayers with different . The dependence of on was fitted (dash curve) by Eq. (9) in Ref. 9.
