The quantum magnet SrCu2(BO3)2 is a physical realisation of the Shastry-Sutherland model - a two-dimensional square lattice, solved to have a ground state of singlets on diagonal bonds. Recent theoretical work suggests that the material should play h

Atomic-scale coexistence of short-range magnetic order and superconductivity in Fe1+ySe0.1Te0.9

Autor: Joachim Deisenhofer, J. Ph. Reid, Peter Wahl, Haibiao Zhou, Antoine Essig, Vladimir Tsurkan, Alois Loidl, Ramakrishna Aluru

Publikováno v: Physical Review Materials. 3

The ground state of the parent compounds of many high-temperature superconductors is an antiferromagnetically ordered phase, where superconductivity emerges when the antiferromagnetic phase transition is suppressed by doping or application of pressur

Sudden reversal in the pressure dependence of Tc in the iron-based superconductor KFe2As2

Autor: Louis Taillefer, A. Juneau-Fecteau, X-G. Luo, M-È. Delage, Nicolas Doiron-Leyraud, S. René de Cotret, Aifeng Wang, Fazel Tafti, J-Ph. Reid, X. H. Chen

Publikováno v: Nature Physics. 9:349-352

Different probes have found different superconducting pairing states in different iron-based high-temperature superconductors. Now transport measurements suggest that pressure drives the superconducting state in KFe2As2 from d-wave to s-wave.

Publikováno v: Physical Review B. 93

In the temperature-concentration phase diagram of most iron-based superconductors, antiferromagnetic order is gradually suppressed to zero at a critical point, and a dome of superconductivity forms around that point. The nature of the magnetic phase
