Magnetic permeability and zone-folded phonons in layered NiPS
André A. A. Silva, Eduardo D. Stefanato, Nicolas M. Kawahala +8
Nickel phosphorus trisulfide (NiPS) stands out as a Mott insulator exhibiting XY-type antiferromagnetic order. In this work, we investigate the electrodynamic response of singl…
Colossal Terahertz Magnetoresistance from Magnetic Polarons in EuZnP
E. Marulanda, M. Dutra, N. M. Kawahala +5
Magnetic polarons can generate colossal magnetoresistance in magnetic semiconductors, yet their terahertz electrodynamics remain largely unexplored. Here we report magneto-terahert…
Optimizing Aperture Geometry in THz-TDS for Accurate Spectroscopy of Quantum Materials
Laura O. Dias, Eduardo D. Stefanato, Nicolas M. Kawahala +1
Terahertz time-domain spectroscopy (THz-TDS) provides a powerful platform for investigating low-energy excitations in quantum materials. Because these materials are often limited i…
Metallicity-driven polar transitions in topological epilayers
Eduardo D. Stefanato, Nicolas M. Kawahala, Bianca A. Kawata +3
Polar metals, materials that exhibit both electric polarization and high conductivity, can also host topological phases. Because free carriers strongly suppress distortive polar or…
