Mean field analysis of a model for superconductivity in an anti-ferromagnetic background

open access: yes, 1998
We study a lattice fermion model for superconductivity in the presence of an anti-ferromagnetic background, described as a fixed external staggered magnetic field. We discuss the possibility that our model provides an effective description of coexistence

Shielding Characteristics of Solenoidal Superconducting Screens Made From HTS Tape, for SFCL Applications

open access: yesIEEE Access, 2023
In the design and prototyping of an Inductive-Resistive Superconductor Fault Current Limiter (IR-SFCL), previously presented by the authors, superconducting screens made from BSCO bulk have been used for shielding the inductive stage of the device.

Evidence for charge delocalization crossover in the quantum critical superconductor CeRhIn5

open access: yesNature Communications, 2023
The nature of charge degrees-of-freedom distinguishes scenarios for interpreting the character of a second order magnetic transition at zero temperature, that is, a magnetic quantum critical point (QCP).

Emergent Magnetism, Heavy Electrons, and Pressure-Induced Reentrant Superconductivity in the Iron Substituted 4d Transition-Metal Sulfides. [PDF]

open access: yesAdv Sci (Weinh)
This work illustrates that magnetic Fe substitution enables systematic modulation of physical properties of the putative unconventional superconductor Rh17S15. Iron doping uncovers delicate competition between weak ferromagnetism, spin‐glass states, heavy‐fermion signatures, and superconductivity.

Effect of heat treatments on superconducting properties and connectivity in K-doped BaFe2As2

open access: yesScientific Reports, 2021
Fe-based superconductors and in particular K-doped BaFe2As2 (K-Ba122) are materials of interest for possible future high-field applications. However the critical current density (J c ) in polycrystalline Ba122 is still quite low and connectivity issues ...

Pressure-Tuned Superconducting Dome and Persistent Charge-Density-Wave Order in NdSeTe<sub>2</sub>. [PDF]

open access: yesAdv Sci (Weinh)
NdSeTe2 exhibits an unusual pressure‐tuned phase diagram in which charge‐density‐wave order does not disappear at optimal superconductivity. Instead, Raman spectroscopy reveals a transformation from long‐range to short‐range correlations that remain invisible to resistivity and persist across the entire superconducting dome.

Transport current and magnetization of Bi-2212 wires above liquid Helium temperature for cryogen-free applications

open access: yesScientific Reports, 2021
Since the discovery of high temperature superconductors, a possible cryogen-free scenario has always been wished. Nowadays, liquid Helium is running out, and it is likely that the cooling by will be a large part of the costs of any superconducting system.
