Single‐Layer Spin‐Orbit‐Torque Magnetization Switching Due to Spin Berry Curvature Generated by Minute Spontaneous Atomic Displacement in a Weyl Oxide

Advanced Materials, Volume 37, Issue 26, July 3, 2025.
Single‐layer magnetization switching with a small critical current density of ≈106 A cm−2 is demonstrated. The strong intrinsic spin Hall effect, causing the switching, is induced by the synergy of the inherent spin‐orbit coupling and the spontaneous oxygen octahedral rotation in SrRuO3.The findings highlight the immense potential for realizing ...

Rosette Spectroscopic Imaging for Whole‐Brain Slab Metabolite Mapping at 7T: Acceleration Potential and Reproducibility

Human Brain Mapping, Volume 46, Issue 4, March 2025.
2D‐/3D‐ whole‐brain slab non‐lipid‐suppression ultra‐short‐TE 1H‐MRSI acquisition schemes were developed using the rosette trajectory at 7T. This method showed excellent intra‐session reproducibility, with the coefficients of variance of major metabolites, like glutamate, below 5%.
