FIG. 1.

(a)-(c) Influence of current pulses on magnetization. In (b) and (c), blue up (down) triangles denote after injection of a positive (negative) current pulse during the positive to negative (+B −B) field sweep, while the corresponding for the negative to positive (−B +B) half is represented by red squares (circles). The asymmetry between the hysteresis loops for the positive to negative and the negative to positive field sweeps is caused by the slightly different paths followed by the magnetization during the time evolution to equilibrium. Insets in (a) schematically show the time sequence of the applied magnetic field and current pulses with both polarities. Current densities are given in units of 1012 A/m2. (d) Dependence of the coercivity (filled squares) and the maximum field (open circles), against which current induces magnetization switching, on current density. Typical hysteretic behavior of regions I, II, and III is given in (a), (b), and (c), respectively.

FIG. 2.

Three dimensional motion of the normalized magnetization under the influence of positive and negative current pulses, with  = 0.3 T and j = 1.5 × 1012 A/m2. The red (blue) arrow on the unit sphere represents the equilibrium orientation of the magnetization after a negative (positive) pulse, whereas the yellow (green) arrow defines the stable direction of the magnetization when the current pulse is present. The yellow (green) curve shows the path of motion for the magnetization after the negative (positive) current pulse is turned off.

FIG. 3.

Time evolution of the normalized magnetization, at  = 0.2 T, excited by a 10 ps square-wave current pulse, whose amplitude is 1.5 × 1012 A/m2. The shaded area signifies the time interval where the current is present.
