Experimental evidence for the importance of Hund's exchange interaction for the incoherence of the charge carriers in iron-based superconductors
J. Fink, E. D. L. Rienks, S. Thirupathaiah +10
Angle-resolved photoemission spectroscopy (ARPES) is used to study the scattering rates of charge carriers from the hole pockets near Gamma in the iron-based high-Tc hole doped sup…
Electronic structure and ultrafast dynamics of FeAs-based superconductors by angle- and time-resolved photoemission spectroscopy
I. Avigo, S. Thirupathaiah, E. D. L. Rienks +17
In this article we review our angle- and time-resolved photoemission studies (ARPES and trARPES) on various ferropnictides.
Multiple Dirac cones at the surface of the topological metal LaBi
Jayita Nayak, Shu-Chun Wu, Nitesh Kumar +8
The rare-earth monopnictide LaBi exhibits exotic magneto-transport properties including an extremely large and anisotropic magnetoresistance. Experimental evidence for topological…
Room temperature tetragonal noncollinear antiferromagnet PtMnGa
S. Singh, S. W. D'Souza, E. Suard +7
Here we present the tetragonal stoichiometric Heusler compound PtMnGa with the noncollinear AFM order stable up to 350 K. It is resolved by the neutron diffraction as a helical…
