Strontium Titanate Capping Layers as Kinetic Regulators of Redox Phase Transitions in Oxide Heterostructures
Pooya Abdollahi, Woo Jin Kim, Keaghan Knight +2
Oxide capping layers are widely used to protect and stabilize thin-film heterostructures, yet their role in governing phase-transition kinetics remains largely unexplored. Here, we…
Selective strain tuning of nonequilibrium multiferroic dynamics in BiFeO
Chenhang Xu, Patrick Liu, Bo Zhang +11
Quantum materials are characterized by intertwined orders, and a fundamental goal in condensed matter physics is to achieve their selective control in such a way that one order par…
Bend Contour Electron Tomography (BCET): Quantitative strain and topography mapping
Henry G. Bell, Chenhang Xu, Arthur McCray +5
Freestanding thin films of quantum materials naturally develop sub-micrometer, nonuniform strain fields that strongly affect their electronic, magnetic, and structural properties i…
Freestanding Antiferromagnetic Oxide Membranes: Synthesis and Characterization of CrO
Ella Blake, Tiffany C. Wang, Yi Cui +8
Antiferromagnetic (AFM) insulators stand out as a promising class of materials for fast switching, energy-efficient magnon-based technology, but our understanding of how to tune th…
Defect-engineered scaling of lead-free ferroelectrics with ultralow-voltage switching
Reza Ghanbari, Jiayue Wang, Harikrishnan KP +9
Scaling ferroelectrics to nanometer thicknesses remains a central challenge for low-power, nonvolatile electronics, as leakage currents increasingly dominate with reduced dimension…
Nearly Isotropic Magnon Transport in Epitaxial Lithium Aluminum Ferrite Thin Films
Yiming Li, Katya Mikhailova, Lerato Takana +9
Low-loss magnetic insulating thin films are promising for information transport via magnons, where isotropic in-plane magnon propagation is desirable. We report nonlocal measuremen…
Designing heterostructures to control oxygen stoichiometry in helimagnetic perovskite strontium ferrite
Jennifer Fowlie, Bernat Mundet, Danilo Puggioni +10
A large challenge in determining the physics of helimagnetic SrFeO3 is in stabilizing the stoichiometric chemical phase over long enough time scales to conduct extensive measuremen…
