Revealing buried ferroelectric topologies by depth-resolved electron diffraction imaging
Ting-Ran Liu, Koushik Jagadish, Xiangwei Guo +10
Nanoscale topological polar textures promise new functionalities for ferroelectric memories and logic, yet their three-dimensional structure and mesoscale organization remain exper…
Spatially modulated morphotropic phase boundaries in a compressively strained multiferroic thin film
Ting-Ran Liu, Xiangwei Guo, Sajid Husain +5
The coexisting rhombohedral-like (R', MA) and tetragonal-like (T', MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and…
Above Room Temperature Ferroelectricity in Epitaxially Strained KTaO3
Tobias Schwaigert, Salva Salmani-Rezaie, Sankalpa Hazra +9
Epitaxial strain is a powerful means to engineer emergent phenomena in thin films and heterostructures. Here, we demonstrate that KTaO3, a cubic perovskite in bulk form, can be epi…
Topological textures and emergent altermagnetic signatures in ultrathin BiFeO3
George Fratian, Maya Ramesh, Xinyan Li +23
Magnetoelectric multiferroics, materials with intrinsically coupled electric polarization and magnetic order, promise ultralow-power switching, nonvolatile memory, and energy-effic…
Low-energy domain wall racetracks with multiferroic topologies
Arundhati Ghosal, Alexander Qualls, Yousra Nahas +13
Conventional racetrack memories move information by pushing magnetic domain walls or other spin textures with spin-polarized currents, but the accompanying Joule heating inflates t…
Colossal enhancement of spin transmission through magnon confinement in an antiferromagnet
Sajid Husain, Maya Ramesh, Xinyan Li +21
Since Felix Bloch's introduction of the concept of spin waves in 1930, magnons (the quanta of spin waves) have been extensively studied in a range of materials for spintronics, par…
