Engineering strong magnetoelectricity using a hexagonal 2D material on electron-doped hexagonal LuFeO
M. J. Swamynadhan, Andrew O'Hara, Saurabh Ghosh +1
Cubic perovskite-structure ABO and AABO-type oxides have been investigated extensively while their hexagonal-structure versions have received minimal…
High-temperature phonons in h-BN: momentum-resolved vibrational spectroscopy and theory
Andrew O'Hara, Benjamin Plotkin-Swing, Niklas Dellby +4
Vibrations in materials and nanostructures at sufficiently high temperatures result in anharmonic atomic displacements, which leads to new phenomena such as thermal expansion and m…
Direct Visualization of Localized Vibrations at Complex Grain Boundaries
Eric R. Hoglund, De-Liang Bao, Andrew O'Hara +7
Grain boundaries (GBs) are a prolific microstructural feature that dominates the functionality of a wide class of materials. The change in functionality at a GB is a direct result…
The origin of insulating and non-ferromagnetic SrRuO3 monolayers
Zeeshan Ali, Zhen Wang, Andrew O'Hara +5
The electro-magnetic properties of ultrathin epitaxial ruthenate films have long been the subject of debate. Here we combine experimental with theoretical investigations of (SrTiO3…
