Achieving field-free current-induced switching of perpendicular magnetization is crucial for the advancement spin–orbit torque magnetic random access memory technology. In our study on Pt/Co/Ru/RuO2(101) system, we have demonstrated via current injection along RuO2[010] axis. We found that system features a tilted easy axis, deviating from out-of-plane orientation toward RuO2[1¯01] direction. The application to this axis generates significant effective field, enabling switching. Our findings...

However, mechanisms typically...
Understanding the physiological processes associated with leaf photosynthetic characteristics and nitrogen (N) assimilation during grain-filling stage are helpful for enhancing utilization efficiency (NUtE) of maize.
