Compression (red arrows) alters crystal symmetry (green arrows), which changes band dispersion (left and right), leading to highly mobile electrons. Credit: Jaimee Janiga, Andrew Sproles, Satoshi Okamoto/ORNL, U.S. Dept. of Energy A team led by the Department of Energy’s Oak Ridge National Laboratory has found a rare quantum material in which electrons move in coordinated […]

Illustration of a magnetic skyrmion that induces an emergent electromagnetic field, yielding the topological Hall effect by deflecting electrons. Nanometer-scale magnetic skyrmions as small as 10 nm were created in LaMnO3/SrIrO3 superlattices where interface symmetry is tailored to increase magnetic exchange interactions. Reearchers discovered a chiral spin texture in 3d-5d transition-metal oxide heterostructures that is […]
Precision synthesis of a CeO2/Y2O3 superlattice nanobrush. The chevron pattern seen from a cross-sectional scanning transmission electron microscopy image of 1.4 m tall bristles comes from alternating stacks of nanometer-thick CeO2 and Y2O3 layers, forming atomically well defined (111) interfaces. Researchers discovered a novel synthesis method to grow nanobrush architectures with interfaces designed to form […]
