Spin-phonon interactions and magnetoelectric coupling in CoO ( = Nb, Ta)
K. Park, J. Kim, S. Choi +10
In order to explore the consequences of spin-orbit coupling on spin-phonon interactions in a set of chemically-similar mixed metal oxides, we measured the infrared vibrational prop…
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…
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…
Electron-beam induced emergence of mesoscopic ordering in layered MnPS
Kevin M. Roccapriore, Nan Huang, Mark P. Oxley +8
Ordered mesoscale structures in 2D materials induced by small misorientations have opened pathways for a wide variety of novel electronic, ferroelectric, and quantum phenomena. Unt…
Chemical bonding and Born charge in 1T-HfS
Sabine N. Neal, Shutong Li, Turan Birol +1
We combine infrared absorption and Raman scattering spectroscopies to explore the properties of the heavy transition metal dichalcogenide 1T-HfS. We employ the LO-TO splitting…
