LLBS simulations of the pulse design in Joule heat assisted STT switching diagrams of the free layer's magnetic moment. Height and width of the switching pulses are shown for and with . Gilbert damping was set to 0.01.
Magnetization dynamics in the operational conditions A, B and B′ (see Fig. 1 ). In (a) and (c), we represent the dynamic behavior at RT. In (b) and (d), we represent the switchings assisted by Joule heating. In (a)–(d) with thick lines is represented and hatched zones correspond to and . In (a) (continuous line and darker hatch) and (b), we have the same shape of the pulse. Also, in (c) and (d), the pulses have the same width and height.
Numerical simulations of switching fields below SW limit. (a) and (b) are showing the STT distortion of the critical curves both for positive and negative currents. Gilbert damping was set to 0.01 and . For comparison, the fall of the switching fields below SW limit due to α and are presented in (c) and (d).
The Joule effect signature, intrinsically connected with the flowing of the polarized current at different lengths of the pulses. The fields are applied almost instantaneous. The Gilbert damping was set to 0.1. In the inset, the distortions for two height of the pulses and the same length are shown. We referred to “extended” SW when was taken into account in the computation.
