Superconducting properties of the spin Hall candidate Ta3Sb with eightfold degeneracy
R. Chapai, A. Rydh, M. P. Smylie +7
We report the synthesis and characterization of phase pure Ta3Sb, a material predicted to be topological with eightfold degenerate fermionic states [Science 353, aaf5037 (2016)] an…
Phenomenological theory of magnetic 90 helical state
A. E. Koshelev
We explore a phenomenological phase diagram for the magnetic helical state with 90 turn angle between neighboring spins in the external magnetic field. Such state is form…
Spin waves and high-frequency response in layered superconductors with helical magnetic structure
A. E. Koshelev
We evaluate the spin-wave spectrum and dynamic susceptibility in a layered superconductors with helical interlayer magnetic structure. We especially focus on the structure in which…
Observing the suppression of superconductivity in RbEuFeAs by correlated magnetic fluctuations
D. Collomb, S. J. Bending, A. E. Koshelev +7
In this letter, we describe quantitative magnetic imaging of superconducting vortices in RbEuFeAs in order to investigate the unique interplay between the magnetic and supe…
Magnetoresistance scaling, disorder, `hot spots' and the origin of -linear resistivity in BaFe(AsP)
Nikola Maksimovic, Ian M. Hayes, Vikram Nagarajan +5
The scaling of -linear magnetoresistance in field and temperature was measured in under-doped (x = 0.19) and optimally-doped (x=0.31)~BaFe(AsP). We analyze t…
Suppression of superconducting parameters by correlated quasi-two-dimensional magnetic fluctuations
A. E. Koshelev
We consider a clean layered magnetic superconductor in which a continuous magnetic transition takes place inside superconducting state and the exchange interaction between supercon…
