FIG. 1.

(a) Coordinate system used in this paper. Panels (b)–(d) illustrate the precessional switching of the magnetization using -field (b) induced cubic anisotropy field reduction (c). Trajectory of the magnetization when subjected to is shown in (d) with material parameters used in the text and a damping constant of (Ref. 12).

FIG. 2.

(a) Switching areas for transition between equilibrium position 1 and 2 . The top (resp. down) dashed area indicates magnetic field points for which switching from 1 (resp. 2) to 2 (resp. 1) is possible for . Insets show magnetic energy as a function of in-plane angle for (without an -field pulse) and (with an -field pulse) in two field points and . (b) Toggle switching critical curves dependence on the cubic anisotropy field .

FIG. 3.

Gray scale maps of -field pulse duration as a function of the magnetic field for a switching starting from position 1 (a) and position 2 (b). Region labeled I (resp. II) refers to magnetization switching with overshoot (resp. undershoot). Dashed white line corresponds to ballistic trajectory of the magnetization.
