Engineering Grain Boundary Commensurability for Ferroelectric Stabilization in Hafnia-Based Films
Chuqiao Shi, Xinyan Li, Xing He +11
Grain boundaries fundamentally dictate the macroscopic properties of polycrystalline materials by breaking long-range symmetry. In ferroelectrics, these structural discontinuities…
Emergence of millimeter-wave resonances in self-assembled ferroelectric metamaterials
Florian Bergmann, Peter Meisenheimer, Aiden Ross +26
Resonators are a key component in modern communications and computing. As demand and technological advances push component requirements into the terahertz regime, there is signific…
Harnessing the polar vortex motion in oxide heterostructures
Pushpendra Gupta, Mohit Tanwani, Qi Xu +7
Polar topology, an analogue of the magnetic topology, serves as a large playground for exotic physical phenomena with a wide range of multifunctional applications. Polar vortices a…
Emergence of Transverse Dielectric Response in Ferroelectric Dielectric Heterostructures
Fernando Gómez-Ortiz, Ramamoorthy Ramesh, Javier Junquera
We report the emergence of a transverse dielectric response in PbTiO/SrTiO superlattices hosting polar vortex structures. Using second-principles simulations, we find t…
Terahertz-field activation of polar skyrons
Huaiyu Wang, Vladimir Stoica, Cheng Dai +27
Unraveling collective modes arising from coupled degrees of freedom is crucial for understanding complex interactions in solids and developing new functionalities. Unique collectiv…
Symmetry-based phenomenological model for magnon transport in a multiferroic
Isaac A. Harris, Sajid Husain, Peter Meisenheimer +9
Magnons carriers of spin information can be controlled by electric fields in the multiferroic BiFeO (BFO), a milestone that brings magnons closer to application in future devic…
Non-volatile spin transport in a single domain multiferroic
Sajid Husain, Isaac Harris, Peter Meisenheimer +22
Antiferromagnets have attracted significant attention in the field of magnonics, as promising candidates for ultralow-energy carriers for information transfer for future computing.…
Designed spin-texture-lattice to control anisotropic magnon transport in antiferromagnets
Peter Meisenheimer, Maya Ramesh, Sajid Husain +14
Spin waves in magnetic materials are promising information carriers for future computing technologies due to their ultra-low energy dissipation and long coherence length. Antiferro…
Non-equilibrium pathways to emergent polar supertextures
Vladimir A. Stoica, Tiannan Yang, Sujit Das +31
Ultrafast stimuli can stabilize metastable states of matter inaccessible by equilibrium means. Establishing the spatiotemporal link between ultrafast excitation and metastability i…
Imaging and characterization of conducting ferroelectric domain walls by photoemission electron microscopy
J. Schaab, I. P. Krug, F. Nickel +9
High-resolution X-ray photoemission electron microscopy (X-PEEM) is a well-established method for imaging ferroelectric domain structures. Here, we expand the scope of application…
