Ferroelectricity in epitaxially strained rhombohedral ZrO2 thin films
J. P. B. Silva, R. F. Negrea, M. C. Istrate +7
Zirconia and hafnia based thin films have attracted tremendous attention in the last decade due to their unexpected ferroelectric behavior at the nanoscale, which facilitates the d…
Noncollinear Magnetic Modulation of Weyl Nodes in Ferrimagnetic MnGa
Cheng-Yi Huang, Hugo Aramberri, Hsin Lin +1
The tetragonal ferrimagnetic MnGa exhibits a wide range of intriguing magnetic properties. Here, we report the emergence of topologically nontrivial nodal lines in the absence…
Effect of dopant ordering on the stability of ferroelectric hafnia
Sangita Dutta, Hugo Aramberri, Tony Schenk +1
Films of all-important compound hafnia (HfO2) can be prepared in an orthorhombic ferroelectric (FE) state that is ideal for applications, e.g. in memories or negative-capacitance f…
Archetypal soft-mode driven antipolar transition in francisite Cu3Bi(SeO3)2O2Cl
Cosme Milesi-Brault, Constance Toulouse, Evan Constable +8
Model materials are precious test cases for elementary theories and provide building blocks for the understanding of more complex cases. Here, we describe the lattice dynamics of t…
Termination Dependent Topological Surface States in Nodal Loop Semimetal HfP2
Christopher Sims, M. Mofazzel Hosen, Hugo Aramberri +11
Symmetry plays a major role in all disciplines of physics. Within the field of topological materials there is a great interest in understanding how the mechanics of crystalline and…
Electric control of the heat flux through electrophononic effects
Juan Antonio Seijas-Bellido, Hugo Aramberri, Jorge Íñiguez +1
We demonstrate a fully electric control of the heat flux, which can be continuously modulated by an externally applied electric field in PbTiO, a prototypical ferroelectric per…
