Two-channel conduction in YbPtBi
M. B. Schilling, A. Löhle, D. Neubauer +4
We investigated transport, magnetotransport, and broadband optical properties of the half-Heusler compound YbPtBi. Hall measurements evidence two types of charge carriers: highly m…
Free-carrier dynamics in AuPb probed by optical conductivity measurements
R. Kemmler, R. Hübner, A. Löhle +5
We measured the optical reflectivity of the Dirac material AuPb in a broad frequency range (30 - 48 000 cm) for temperatures between 9 and 300 K. The optical conductiv…
A light pseudoscalar in a model with lepton family symmetry O(2)
W. Grimus, L. Lavoura, D. Neubauer
We discuss a realization of the non-abelian group O(2) as a family symmetry for the lepton sector. The reflection contained in O(2) acts as a mu-tau interchange symmetry, enforcing…
Optical conductivity of the Weyl semimetal NbP
D. Neubauer, A. Yaresko, Weiwu Li +7
The optical properties of (001)-oriented NbP single crystals have been studied in a wide spectral range from 6 meV to 3 eV from room temperature down to 10 K. The itinerant carrier…
Persistent detwinning of iron pnictides by small magnetic fields
S. Zapf, C. Stingl, K. W. Post +11
Our comprehensive study on EuFeAs reveals a dramatic reduction of magnetic detwinning fields compared to other AFeAs (A = Ba, Sr, Ca) iron pnictides by indirect mag…
Reentrant phases in electron-doped : spin glass and superconductivity
A. Baumgartner, D. Neubauer, S. Zapf +4
We report evidence for a reentrant spin glass phase in electron-doped single crystals and first traces of the superconductivity re-entrance in optics. In…
