Curvature-Controlled Polarization in Adaptive Ferroelectric Membranes
Greta Segantini, Ludovica Tovaglieri, Chang Jae Roh +12
In this study, we explore the ferroelectric domain structure and mechanical properties of PbTiO-based membranes, which develops a well-ordered and crystallographic-oriented rip…
Electron-Beam Writing of Atomic-Scale Reconstructions at Oxide Interfaces
Greta Segantini, Chih-Ying Hsu, Carl Willem Rischau +6
The epitaxial growth of complex oxides enables the production of high-quality films, yet substrate choice is restricted to certain symmetry and lattice parameters, thereby limiting…
Controlling magnetism with light in a zero orbital angular momentum antiferromagnet
Mattias Matthiesen, Jorrit R. Hortensius, Samuel Mañas-Valero +6
Antiferromagnetic materials feature intrinsic ultrafast spin dynamics, making them ideal candidates for future magnonic devices operating at THz frequencies. A major focus of curre…
Self-sealing complex oxide resonators
Martin Lee, Martin Robin, Ruben Guis +9
Although 2D materials hold great potential for next-generation pressure sensors, recent studies revealed that gases permeate along the membrane-surface interface that is only weakl…
Ultrafast phononic switching of magnetization
A. Stupakiewicz, C. S. Davies, K. Szerenos +6
Identifying an efficient pathway to change the order parameter via a subtle excitation of the coupled high-frequency mode is the ultimate goal of the field of ultrafast phase trans…
Controlling the anisotropy of a van der Waals antiferromagnet with light
D. Afanasiev, J. R. Hortensius, M. Matthiesen +9
Magnetic van der Waals materials provide an ideal playground for exploring the fundamentals of low-dimensional magnetism and open new opportunities for ultrathin spin processing de…
