Non-reciprocal Slonczewski linear modes.

(a,b) Example of the spatial profile of the reciprocal and nonreciprocal Slonczweski spin waves, respectively, calculated for I = 5.28 A and D = 0.0 and 1.5 mJ/m2. respectively. (c) Oscillation frequency of the excited SLM as a function of D for two values of the driving current. (d) Wave numbers along the −x and +x directions as functions of D for two values of current; (e) Difference between the wave numbers along the positive and negative x-directions as a function D for the same two values of current (solid lines) and the same difference calculated analytically from Eq. (2) (dashed line).
