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…
Novel Family of Topological Semimetals with Butterfly-like Nodal Lines
Xiaoting Zhou, Chuang-Han Hsu, Hugo Aramberri +6
In recent years, the exotic properties of topological semimetals (TSMs) have attracted great attention and significant efforts have been made in seeking for new topological phases…
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…
Antiferroelectricity in a family of pyroxene-like oxides with rich polymorphism
Hugo Aramberri, Jorge Íñiguez
Antiferroelectrics have potential applications in energy conversion and storage, but are scarce, particularly among oxides that otherwise display rich ferroic behaviours. Are we ov…
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…
