Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Xuepeng Wang, Xuepeng Wang, , , | Summary: Skyrmions are emergent many-body excitations that lie at the heart of both multi-component quantum Hall-like systems and deconfined quantum criticality. In a companion article (X. Wang et al., arXiv:2507.22971), we studied a microscopic time-reversal symmetric model of tunable interacting […]
Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Xiaoxi Huang, Xiaoxi Huang, , , | Summary: To achieve efficient anti-damping switching of nanoscale magnetic memories with perpendicular magnetic anisotropy using spin-orbit torque requires that the anti-damping spin-orbit torque have a strong out-of-plane component. The spin anomalous Hall effect and the planar Hall effect spin […]

Kavli Affiliate: Richard D. Robinson | First 5 Authors: Hongjin Du, Hongjin Du, , , | Summary: Semiconductor magic-size clusters (MSCs) are atomically precise nanoparticles exhibiting unique size-dependent properties, but their ultrasmall dimensions hinder structural characterization, limiting our understanding of their formation and stability. A few MSC structures have been fully resolved, revealing either bulk-like […]
Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Yongjian Tang, Yongjian Tang, , , | Summary: Spin Hall magnetoresistance (SMR) measurements provide a way to probe the surface spin structure of insulating magnetic materials. Such measurements produce resistance signals of the form $Delta$R $propto$ cos[2($alpha$-$alpha$$_0$)], where $alpha$ is the angle between the current and […]
Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Xiaoxi Huang, Xiaoxi Huang, , , | Summary: We report measurements of the current-induced spin torque produced by the delafossite antiferromagnet PdCrO2 and acting on an adjacent ferromagnetic permalloy layer. The spin torque increases strongly as the temperature is reduced through the Neel temperature, when the […]

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Benjamin Z. Gregory, Benjamin Z. Gregory, , , | Summary: Excitement about the magnetic and electronic properties of RuO$_2$ is growing, fueled by reports of antiferromagnetism, strain-induced superconductivity, and its recent classification as a member of a newly proposed magnetic class, altermagnets, with RuO$_2$ widely regarded […]
Kavli Affiliate: Darrell G. Schlom | First 5 Authors: , , , , | Summary: The search for thin film electro-optic (EO) materials that can retain superior performance under cryogenic conditions has become critical for quantum computing. Barium titanate thin films show large linear EO coefficients in the tetragonal phase at room temperature, which is […]
Kavli Affiliate: Nicole A. Benedek | First 5 Authors: Ethan T. Ritz, Ethan T. Ritz, , , | Summary: We present a technique for partitioning the total energy from a semi-local density functional theory calculation into contributions from individual electronic states in a localized Wannier basis. We use our technique to reveal the key role […]
