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…
Terahertz Lattice Imprint of a Hidden Multipolar Ordering Transition in GdRuO
Nicolas M. Kawahala, Rafael L. Sabainsk, Esteban Marulanda +2
Magnetic order carried by higher-rank multipoles produces no net moment and couples only weakly to conventional dipolar probes. Recently, the lattice has been proposed as an altern…
Engineering a Correlated Narrow-Gap Semiconductor: Effects of Ga Substitution in EuZnP
M. Dutra, E. Marulanda, G. G. Vasques +11
The effect of Ga substitution on the electronic, magnetic, and low-energy responses of the Zintl phase EuZnP is investigated by electrical transport, electron spin resonanc…
Windowing in terahertz time-domain spectroscopy: resolving resonances in thin-film samples
Esteban Marulanda, Fernanda L. Costa, Nicolas M. Kawahala +1
Terahertz time-domain spectroscopy (THz-TDS) has become a powerful tool for investigating the optical properties of thin films, offering direct access to the complex permittivity i…
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…
