The role of 245 phase in alkaline iron selenide superconductors revealed by high pressure studies

Peiwen Gao, Rong Yu, Liling Sun +15

Here we show that a pressure of about 8 GPa suppresses both the vacancy order and the insulating phase, and a further increase of the pressure to about 18 GPa induces a second tran…

Observation of Temperature-Induced Crossover to an Orbital-Selective Mott Phase in AFeSe (A=K, Rb) Superconductors

Ming Yi, Donghui Lu, Rong Yu +13

In this work, we study the AFeSe (A=K, Rb) superconductors using angle-resolved photoemission spectroscopy. In the low temperature state, we observe an orbital-de…

Nematic and meta-nematic transitions in the iron pnictides

S. Kasahara, H. J. Shi, K. Hashimoto +8

Strongly interacting electrons can exhibit novel collective phases, among which the electronic nematic phases are perhaps the most surprising as they spontaneously break rotational…

Type-I superconductivity in ScGa3 and LuGa3 single crystals

E. Svanidze, E. Morosan

We present evidence of type-I superconductivity in single crystals of ScGa3 and LuGa3, from magnetization, specific heat, and resistivity measurements: low critical temperatures Tc…

Superconductivity in Ce- and U-based "122" heavy-fermion compounds

Oliver Stockert, Stefan Kirchner, Frank Steglich +1

This review discusses the heavy-fermion superconductivity in Ce- and U-based compounds crystallizing in the body-centered tetragonal ThCr2Si2 structure. Special attention will be p…

Magnetically driven superconductivity in CeCu2Si2

O. Stockert, J. Arndt, E. Faulhaber +8

The origin of unconventional superconductivity, including high-temperature and heavy-fermion superconductivity, is still a matter of controversy. Spin excitations instead of phonon…

Type I Superconductivity in YbSb2 Single Crystals

Liang L. Zhao, Stefan Lausberg, H. Kim +4

We present evidence of type I superconductivity in YbSb2 single crystals, from DC and AC magnetization, heat capacity and resistivity measurements. The critical temperature and cri…
