CISS implies that the spin preference of chiral structures persists upon injection of pure spin currents and can act as a spin analyzer without the need for a ferromagnet. Here, we report an anomalous spin current absorption in chiral metal oxides that manifests a colossal anisotropic nonlocal Gilbert damping with a maximum-to-minimum ratio of up to 1000%. A twofold symmetry of the damping is shown to result from differential spin transmission and backscattering that arise from chirality-induced spin splitting along the chiral axis. These studies reveal the rich interplay of chirality and spin dynamics and identify how chiral materials can be implemented to direct the transport of spin current.}, number={18}, journal={SCIENCE ADVANCES}, author={Sun, Rui and Wang, Ziqi and Bloom, Brian P. and Comstock, Andrew H. and Yang, Cong and McConnell, Aeron and Clever, Caleb and Molitoris, Mary and Lamont, Daniel and Cheng, Zhao-Hua and et al.}, year={2024}, month={May} }

In this work, we demonstrate REE at Pt/ferroelectric interfaces using the recently elucidated spin-Hall Hanle effects (SHHE), in which a Larmor precession of spin polarization in a diffusion process from the interface manifest as magnetoresistance and Hall effect. We show that REE leads to a three-fold enhancement of the effective spin Hall angle in ferroelectric interface Pt/h-LuFeO3 compared to that of Pt /Al2O3, although the difference in the spin relaxation time is negligible. Modeling using SHHEs involving REE as an additional source of interfacial polarization suggests that REE can lead to an interfacial spin Hall angle (~0.3) that is one order of magnitude larger than the bulk value of Pt. Our results demonstrate that a ferroelectric interface can produce large spin-charge conversion and that SHHEs are a sensitive tool for characterizing interfacial spin transport properties.}, number={24}, journal={PHYSICAL REVIEW B}, author={Li, Jing and Comstock, Andrew H. and Mcconnell, Aeron and Li, Xin and Yun, Yu and Sun, Dali and Xu, Xiaoshan}, year={2023}, month={Dec} }
