Topological Surface Magnetism and Neel Vector Control in a Magnetoelectric Antiferromagnet
Kai Du, Xianghan Xu, Choongjae Won +5
Antiferromagnetic states with no stray magnetic fields can enable high-density ultra-fast spintronic technologies. However, the detection and control of antiferromagnetic Neel vect…
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…
Ultrafast Modulations And Detection of a Ferro-rotational Charge Density Wave Using Time-resolved Electric Quadrupole Second Harmonic Generation
Xiangpeng Luo, Dimuthu Obeysekera, Choongjae Won +7
We show the ferro-rotational nature of the commensurate charge density wave (CCDW) in - and track its dynamic modulations by temperature-dependent and time-reso…
Large Orbital Magnetic Moment and Strong Perpendicular Magnetic Anisotropy in Heavily Intercalated FeTiS
Goro Shibata, Choongjae Won, Jaewook Kim +7
Titanium disulfide TiS, which is a member of the layered transition-metal dichalcogenides with the 1T-CdI-type crystal structure, is known to exhibit a wide variety of magn…
From first- to second-order phase transitions in hybrid improper ferroelectrics through entropy stabilisation
Fernando Pomiro, Chris Ablitt, Nicholas C. Bristowe +4
Hybrid improper ferroelectrics (HIFs) have been intensely studied over the last few years to gain understanding of their temperature induced phase transitions and ferroelectric swi…
Infrared nano-spectroscopy of ferroelastic domain walls in hybrid improper ferroelectric CaTiO
K. A. Smith, E. A. Nowadnick, S. Fan +14
Ferroic materials are well known to exhibit heterogeneity in the form of domain walls. Understanding the properties of these boundaries is crucial for controlling functionality wit…
