Electric field controlled spin transport in a topological insulator interfaced with a ferroelectric antiferromagnet
Yogesh Kumar, Pushpendra Gupta, Xinyan Li +14
Topological insulators have been explored extensively for spin-charge interconversion via magnetic interfaces, yet the true response of their spin-charge conversion, particularly i…
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…
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…
Mechanical Control of Polar Order
Pushpendra Gupta, Peter Meisenheimer, Xinyan Li +5
BiFeO3 is a model multiferroic in which the ferroelectric polarization is coupled to ferroelastic lattice distortions, yet deterministic control of its domain structure remains lim…
Anisotropic magnon transport in an antiferromagnetic trilayer heterostructure: is BiFeO an altermagnet?
Sajid Husain, Maya Ramesh, Qian Song +18
Magnons provide a route to ultra-fast transport and non-destructive readout of spin-based information transfer. Here, we report magnon transport and its emergent anisotropic nature…
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…
