Current-induced perpendicular effective magnetic field in magnetic heterostructures

Qianbiao Liu et al.

Summary: In this study, we report the discovery and profound impacts of a significant effective perpendicular magnetic field that can arise from asymmetric current spreading within magnetic microstrips and Hall bars. This finding challenges the widely assumed characteristics of an external-magnetic-field-free flow of sigma(z), and highlights the importance of considering current spreading effects in the analysis of spin polarizations and spin-orbit torques in magnetic heterostructures. Technologically, our results provide a novel and universally accessible mechanism for efficient, scalable, and external-magnetic-field-free magnetization switching in memory and computing technologies.

Large spin Hall angle enhanced by nitrogen incorporation in Pt films

Zhan Xu et al.

Summary: Introducing nitrogen into the Pt thin film enhances the spin Hall angle at the CoFeB/Pt interface, with a non-monotonic variation as a function of the amount of nitrogen gas introduced. The enhancement is mainly attributed to the increase in spin-dependent scattering at the interface, with a decrease in effective magnetic damping as nitrogen amount increases. Additionally, improved interfacial spin transparency and enhanced linewidth modulation are observed after the introduction of nitrogen.

Summary: Efficient charge-spin interconversion is crucial for understanding the functionalities of spin-orbit torque in energy-efficient and high-speed spintronic devices. A new spin Hall material, Pt(S), is reported in this study, demonstrating significantly higher conversion efficiency compared to pristine Pt, along with large spin Hall angle and viable electrical and spin Hall conductivity.
