Revisiting the symmetry and optical phonons of altermagnetic -MnTe
Ece Uykur, Marcos V. Gonçalves-Faria, Sahana Rößler +5
Using infrared (IR) and Raman spectroscopies combined with high-resolution x-ray diffraction, we address several controversial aspects of altermagnetic -MnTe. We show that mecha…
Low-field magnetization processes of hexagonal easy-plane altermagnet -MnTe
Sahana Rößler, Victoria Ginga, Marcus Schmidt +5
Single crystals of -MnTe were synthesized by chemical vapor transport using iodine as the transport reagent. Structural characterization by powder x-ray diffraction confirmed th…
Magnetic and electronic properties of EuInSb
M. Victoria Ale Crivillero, Sahana Rößler, S. Granovsky +5
The intermetallic compound EuInSb, an antiferromagnetic material with nonsymmorphic crystalline structure, is investigated by magnetic, electronic transport and specifi…
Impurity-induced bound states inside the superconducting gap of FeSe
Lin Jiao, Sahana Rößler, Cevriye Koz +4
We investigate the local density of states in the vicinity of a native dumbbell defect arising from an Fe vacancy in FeSe single crystals. The tunneling spectra close to the impuri…
Synthesis and Crystal Growth of Tetragonal Fe1.00Se
Cevriye Koz, Marcus Schmidt, Horst Borrmann +6
Single crystals of tetragonal Fe1.00Se were grown from polycrystalline material by chemical vapor transport reaction at temperatures below 723 K using AlCl3 as transport additive.…
Disorder-driven electronic localization and phase separation in superconducting Fe1+yTe0.5Se0.5 single crystals
S. Rößler, Dona Cherian, S. Harikrishnan +6
We have investigated the influence of Fe-excess on the electrical transport and magnetism of Fe1+yTe0.5Se0.5 (y=0.04 and 0.09) single crystals. Both compositions exhibit resistivel…
