The current-induced spin-orbit torque(SOT) is one of the most promising ways for high speed and low power spintronics devices. However, the mechanism of SOT driven magnetization reversal, especially the role of the field-like torque(FLT), is still unclear. Here, we report the observed promotion and suppression of switching by FLT, which depends on the relative direction of FLT and spin polarization. Our results reveal that the FLT could modulate the switching speed and power consumption by affecting the work done by the damping-like torque, and leads two different reversal dynamical paths during the ***, the origin of incubation time in SOT induced switching is clarified simultaneously.

Spin-orbit torque(SOT)has been considered as one of the promising technologies for the next-generation magnetic random access memory(MRAM).So far,SOT has been widely utilized for inducing various modes of magnetization ***,it is a challenge that so many multiple modes of magnetization switching are integrated *** we propose a method of implementing both unipolar switching and bipolar switching of the perpendicular magnetization within a single SOT *** mode of switching can be easily changed by tuning the amplitude of the applied *** show that the field-like torque plays an important role in switching *** field-like torque induces the precession of the magnetization in the case of unipolar switching,however,the field-like torque helps to generate an effective zcomponent torque in the case of bipolar *** addition,the influence of key parameters on the mode of switching is discussed,including the field-like torque strength,the bias field,and the current *** proposal can be used to design novel reconfigurable logic circuits in the near future.
