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 […]

Discovery of Dynamical Heterogeneity in a Supercooled Magnetic Monopole Fluid

Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Jahnatta Dasini, Chaia Carroll, Chun-Chih Hsu, Hiroto Takahashi, Jack Murphy | Summary: Dynamical heterogeneity in which transitory local fluctuations occur in the conformation and dynamics of constituent particles, is essential for evolution of supercooled liquids into the glass state. Yet its microscopic spatiotemporal phenomenology has […]
