Rigidity transitions in anisotropic networks happen in multiple steps

Kavli Affiliate: Itai Cohen | First 5 Authors: William Y. Wang, Stephen J. Thornton, Bulbul Chakraborty, Anna Barth, Navneet Singh | Summary: We study how the rigidity transition in a triangular lattice changes as a function of anisotropy by preferentially filling bonds on the lattice in one direction. We discover that the onset of rigidity […]

Defect Landscape Engineering to Tune Skyrmion-Antiskyrmion Systems in FeGe

Kavli Affiliate: David A. Muller | First 5 Authors: Jiangteng Liu, Ryan Schoell, Xiyue S. Zhang, Hongbin Yang, M. B. Venuti | Summary: A promising architecture for next-generation, low energy spintronic devices uses skyrmions — nanoscale whirlpools of magnetic moment — as information carriers. Notably, schemes for racetrack memory have been proposed in which skyrmions […]

Electron ptychography reveals a ferroelectricity dominated by anion displacements

Kavli Affiliate: David A. Muller | First 5 Authors: Harikrishnan K. P., Ruijuan Xu, Kinnary Patel, Kevin J. Crust, Aarushi Khandelwal | Summary: Sodium niobate, a lead-free ferroic material, hosts delicately-balanced, competing order parameters, including ferroelectric states that can be stabilized by epitaxial strain. Here, we show that the resulting macroscopic ferroelectricity exhibits an unconventional […]

Experimental tests of the full spin torque conductivity tensor in epitaxial IrO2 thin films

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Michael Patton, Daniel A. Pharis, Gautam Gurung, Xiaoxi Huang, Gahee Noh | Summary: Unconventional spin-orbit torques arising from electric-field-generated spin currents in anisotropic materials have promising potential for spintronic applications, including for perpendicular magnetic switching in high-density memory applications. Here we determine all the independent elements […]
