Landau level spectroscopy in current solid state physics
Ana Akrap, Milan Orlita
Landau level spectroscopy plays an important role in modern condensed-matter physics. In this technique, electrons in a solid are subjected to quantizing magnetic fields and probed…
Magneto-optical response of magnetic semiconductors EuCd2X2 (X= P, As, Sb)
S. Nasrallah, D. Santos-Cottin, F. Le Mardele +16
In this study, we identify EuCd2X2 (for X = P, As, Sb) as a series of magnetic semiconductors. We examine how the band gap of the series responds to X changing from phosphorus (P),…
Revealing the KH2PO4 soft-mode coupling mechanism with infrared spectroscopy under pressure
D. Santos-Cottin, S. Nasrallah, F. Capitani +4
We measured the far-infrared reflectivity of a KH2PO4 single crystal up to pressures of 2 GPa in the ferroelectric and paraelectric phases. We find that the nu4 vibrational mode of…
Evidence of 3D Dirac conical bands in TlBiSSe by optical and magneto-optical spectroscopy
F. Le Mardelé, J. Wyzula, I. Mohelsky +15
TlBiSSe is a rare realization of a 3D semimetal with a conically dispersing band that has an optical response which is well isolated from other contributions in a broad range of ph…
EuCdAs: a magnetic semiconductor
D. Santos-Cottin, I. Mohelský, J. Wyzula +18
EuCdAs is now widely accepted as a topological semimetal in which a Weyl phase is induced by an external magnetic field. We challenge this view through firm experimental ev…
Magnetic freeze-out and anomalous Hall effect in ZrTe
Adrien Gourgout, Maxime Leroux, Jean-Loup Smirr +10
The ultra-quantum limit is achieved when a magnetic field confines an electron gas in its lowest spin-polarised Landau level. Here we show that in this limit, electron doped ZrTe$_…
