Pseudogap phase of cuprate superconductors confined by Fermi surface topology
N. Doiron-Leyraud, O. Cyr-Choinière, S. Badoux +15
The properties of cuprate high-temperature superconductors are largely shaped by competing phases whose nature is often a mystery. Chiefly among them is the pseudogap phase, which…
The ab initio study of unconventional superconductivity in CeCoIn and FeSe
Andrzej Ptok, Konrad J. Kapcia, Przemysław Piekarz +1
Electronic structure and the shape of the Fermi surface are known to be of fundamental importance for the superconducting instability in real materials. We demonstrate that such an…
Dynamics of trapped magnetic flux in superconducting FeTe0.65Se0.35
S. I. Bondarenko, A. N. Bludov, V. P. Koverya +6
The magnetic moment in the superconducting and normal state of a crystalline FeTe0.65Se0.35 superconductor, grown by the Bridgman's method with relatively high growth rate, was mea…
Pressure-induced magnetic collapse and metallization of
Pavel G. Naumov, Kai Filsinger, Sergii I. Shylin +8
The crystal structure, magnetic ordering, and electrical resistivity of TlFe1.6Se2 were studied at high pressures. Below ~7 GPa, TlFe1.6Se2 is an antiferromagnetically ordered semi…
Magnetic Lifshitz transition and its consequences in multi-band iron-based superconductors
Andrzej Ptok, Konrad J. Kapcia, Agnieszka Cichy +2
In this paper we address Lifshitz transition induced by applied external magnetic field in a case of iron-based superconductors, in which a difference between the Fermi level and t…
Saturation of resistivity and Kohler's rule in Ni-doped LaSrCuO cuprate
A. Malinowski, V. L. Bezusyy, P. Nowicki
We present the results of electrical transport measurements of LaSrCuNiO thin single-crystal films at magnetic fields up to 9 T. Adding Ni imp…
