Recently, experimental results have demonstrated that perpendicular magnetic tunnel junction (p-MTJ) with the antiferromagnetic(AFM)/ferromagnetic (FM)/oxide structure can achieve field-free spin-orbit torque (SOT) switching since AFM metal strip not only generate SOT, but also provide an exchange bias (HEX), making it suitable for practical applications. However, owing to HEX is weak, such SOT incomplete, thus resulting in severe reliability. In addition, a large current (ISOT) required,...

Comprehensive Summary The nickel‐rich layered ternary cathode material (NCM) has been extensively studied due to its high specific capacity and low cost. Nevertheless, with the increase of Ni content, unstable structure NCM gradually become prominent. Residual alkali on surface Li + /Ni 2+ mixing before cycling, phase change, transition metal ions dissolution, microcracking, other issues during cycle, are primary causes for fast fading Ni‐rich materials. In this study, Sc 3+ is doped into...

Magnetic random-access memory, recognized as a breakthrough in spintronics, demonstrates substantial potential for next-generation nonvolatile memory and logic devices due to its unique magnetization-switching mechanism.
