Direct evidence for two-gap superconductivity in hydrogen-intercalated titanium diselenide
Erik Piatti, Gaia Gavello, Giovanni A. Ummarino +5
Transition-metal dichalcogenides (TMDs) offer an extremely rich material platform in the exploration of unconventional superconductivity. The unconventional aspects include exotic…
Superconductivity of Co-Doped CaKFe4As4 Investigated via Point-Contact Spectroscopy and London Penetration Depth Measurements
Erik Piatti, Daniele Torsello, Francesca Breccia +3
The iron-based superconductors (IBSs) of the recently discovered 1144 class, unlike many other IBSs, display superconductivity in their stoichiometric form and are intrinsically ho…
Unusually weak irradiation effects in anisotropic iron-based superconductor RbCa2Fe4As4F2
Daniele Torsello, Erik Piatti, Michela Fracasso +7
We report on the effects of 3.5 MeV proton irradiation in RbCaFeAsF, an iron-based superconductor with unusual properties in between those of the pnictides and of t…
A model for critical current effects in point-contact Andreev-reflection spectroscopy
Dario Daghero, Erik Piatti, Nikolai D. Zhigadlo +1
It is well known that point-contact Andreev reflection spectroscopy provides reliable measurements of the energy gap(s) in a superconductor when the contact is in the ballistic or…
Spectroscopic studies of the superconducting gap in the 12442 family of iron-based compounds
Erik Piatti, Daniele Torsello, Gianluca Ghigo +1
The iron-based compounds of the so-called 12442 family are very peculiar in various respects. They originate from the intergrowth of 122 and 1111 building blocks, display a large i…
Nodal multigap superconductivity in the anisotropic iron-based compound RbCa2Fe4As4F2
Daniele Torsello, Erik Piatti, Giovanni A. Ummarino +5
The 12442 compounds are a recently discovered family of iron-based superconductors, that share several features with the cuprates due to their strongly anisotropic structure, but a…
