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…
Mind the Gap -- Imaging Buried Interfaces in Twisted Oxide Moirés
Harikrishnan KP, Xin Wei, Chia-Hao Lee +10
The ability to tune electronic structure in twisted stacks of two-dimensional (2D) materials has motivated the exploration of similar moiré physics with twisted oxide membranes. D…
Microscopic mechanisms of flexoelectricity in oxide membranes
Harikrishnan KP, Varun Harbola, Jaehong Choi +9
Modern electromechanical actuators and sensors rely on the piezoelectric effect that linearly couples strain and electric polarization. However, this effect is restricted to materi…
