We have investigated the effects of lead (Pb) additions (x) up to 40 wt.% (x = 0-0.4) on the structure, electrical properties, and magnetic properties of FeSe0.5Te0.5 superconductor. The samples were prepared by the solid-state reaction method and ch

Topological Lifshitz transition in Weyl semimetal NbP decorated with heavy elements

Autor: Wadge, Ashutosh S, Kowalski, Bogdan J, Autieri, Carmine, Iwanowski, Przemysław, Hruban, Andrzej, Olszowska, Natalia, Rosmus, Marcin, Kołodziej, Jacek, Wiśniewski, Andrzej

Studies of the Fermi surface modification after in-situ covering NbP semimetal with heavy elements Pb and Nb ultrathin layers were performed by means of angle-resolved photoemission spectroscopy (ARPES). First, the electronic structure was investigat

Temperature driven spin-zero effect in TaAs$_2$

Autor: Alam, Md Shahin, Tanwar, P. K., Dybko, Krzysztof, Wadge, Ashutosh S., Iwanowski, Przemyslaw, Wisniewski, Andrzej, Matusiak, Marcin

Publikováno v: J. Phys. Chem. Solids, 170, 110939 (2022)

The electrical and thermo-electrical transport effects of the TaAs$_2$ semimetal were measured in a magnetic field applied along [-2 0 1] direction. The resulting field dependences of the resistivity as well as the Hall, Seebeck and Nernst coefficien
