From Narrow-gap Semiconductor to Metallic Altermagnet: Optical Fingerprints of Co-Doped FeSb2
R. Mathew Roy, M. Povolotskiy, J. Kirschke +11
The realization of bulk metallic altermagnetism has remained elusive despite the growing number of candidate materials. Here, we present evidence that moderate cobalt substitution…
Interrelationships between nematicity, antiferromagnetic spin fluctuations and superconductivity: Role of hotspots in FeSeS revealed by high pressure Se NMR study
K. Rana, D. V. Ambika, S. L. Bud'ko +3
The sulfur-substituted FeSe, FeSeS, is one of the unique systems that provides an independent tunability of nematicity, antiferromagnetism and superconductivity unde…
Subdominant -wave interaction in superconducting CaKFeAs?
Daniel Jost, Jan-Robin Scholz, Ulrike Zweck +5
We report inelastic light scattering results on the stoichiometric and fully ordered superconductor CaKFeAs as a function of temperature and light polarization. In the ener…
Imaging Orbital-selective Quasiparticles in the Hund's Metal State of FeSe
Andrey Kostin, Peter O. Sprau, Andreas Kreisel +6
Strong electronic correlations, emerging from the parent Mott insulator phase, are key to copper-based high temperature superconductivity (HTS). By contrast, the parent phase of ir…
Pseudogap Behavior of the Nuclear Spin-lattice Relaxation Rate in FeSe Probed by Se-NMR
Anlu Shi, Takeshi Arai, Shunsaku Kitagawa +7
We conducted Se-nuclear magnetic resonance studies of the iron-based superconductor FeSe in magnetic fields of 0.6 to 19 T to investigate the superconducting and normal-stat…
Nematicity, magnetism and superconductivity in FeSe
Anna E. Böhmer, Andreas Kreisel
Iron-based superconductors are well known for their complex interplay between structure, magnetism and superconductivity. FeSe offers a particularly fascinating example. This mater…
