Query: All-Linear Multistate Magnetic Switching Induced by Electrical Current   We present an alternative mechanism to control the domain wall motion, whose
directions are manipulated by the amplitude of electrical currents when
modulating the ratio of D/A (constants of Dzyaloshinskii-Moriya interaction
over exchange interaction). To confirm this mechanism, we observe this type of
domain wall motion and demonstrate linear magnetic switching without hysteresis
effect via adjusting the D/A of Ta/Pt/Co/Ta multilayer device with ion
implantations. We further find field-free biased and chirally controllable
multistate switching at the lateral interface of ion exposed and unexposed
area, which is due to the current induced Neel wall motion and a strong
exchange coupling at this interface.
