Nonreciprocal directional dichroism at telecom wavelengths
K. Park, M. O. Yokosuk, M. Goryca +7
Magnetoelectrics with ultra-low symmetry and spin-orbit coupling are well known to display a number of remarkable properties including nonreciprocal directional dichroism. As a pol…
Band-Mott mixing hybridizes the gap in FeMoO
K. Park, G. L. Pascut, G. Khanal +9
We combined optical spectroscopy and first principles electronic structure calculations to reveal the charge gap in the polar magnet FeMoO. Iron occupation on the octah…
Vibrational properties of CuInP2S6 across the ferroelectric transition
Sabine N. Neal, Sobhit Singh, Xiaochen Fang +6
In order to explore the properties of a two-sublattice ferroelectric, we measured the infrared and Raman scattering response of CuInP2S6 across the ferroelectric and glassy transit…
Vibrational fingerprints of ferroelectric hafnia
Shiyu Fan, Sobhit Singh, Xianghan Xu +6
Hafnia (HfO2) is a promising material for emerging chip applications due to its high-k dielectric behaviour, suitability for negative capacitance heterostructures, scalable ferroel…
