Coexistence of ferromagnetism and superconductivity in a superconducting alloy

Physica, 1974
Abstract A model for a superconducting alloy doped with magnetic impurities is solved exactly. The model consists of a combination of the BCS model and the Zener s-d exchange-interaction model. Its behaviour appears to be strongly dependent on the impurity concentration and the coupling parameters belonging to the BCS model and the s-d exchange ...

Covalent surface modifications and superconductivity of two-dimensional metal carbide MXenes

Science, 2020
Modifying MXene surfaces Unlike graphene and transition-metal dichalcogenides, two-dimensional transition-metal carbides (MXenes) have many surface sites that can be chemically modified. Etching of the aluminum layer of a parent MAX phase Ti3AlC2 layered

Superconductivity in 5.0° twisted bilayer WSe2

Nature
The discovery of superconductivity in twisted bilayer and trilayer graphene1, 2, 3, 4–5 has generated tremendous interest. The key feature of these systems is an interplay between interlayer coupling and a moiré superlattice that gives rise to low-energy

Signatures of chiral superconductivity in rhombohedral graphene

Nature
Chiral superconductors are unconventional superconducting states that break time-reversal symmetry spontaneously and typically feature Cooper pairing at non-zero angular momentum.

Superconductivity, superfluidity and quantum geometry in twisted multilayer systems

Nature Reviews Physics, 2021
Superconductivity has been observed in moiré systems such as twisted bilayer graphene, which host flat, dispersionless electronic bands. In parallel, theory work has discovered that superconductivity and superfluidity of flat-band systems can be made ...

Tunable superconductivity in electron- and hole-doped Bernal bilayer graphene

Nature
Graphene-based, high-quality, two-dimensional electronic systems have emerged as a highly tunable platform for studying superconductivity1–21. Specifically, superconductivity has been observed in both electron- and hole-doped twisted graphene moiré ...

Superconducting Phosphorus

Science, 1968
Phosphorus, the element itself, becomes superconducting near 4.7°K and at pressures exceeding 100 kilobars. This constitutes one of the four last missing links in the proof that superconductivity is normal behavior for every truly metallic sp element. The three remaining ones are arsenic, sulfur, and iodine.

Superconductivity at 250 K in lanthanum hydride under high pressures

Nature, 2018
With the discovery1 of superconductivity at 203 kelvin in H3S, attention returned to conventional superconductors with properties that can be described by the Bardeen–Cooper–Schrieffer and the Migdal–Eliashberg theories.

Engineered platforms for topological superconductivity and Majorana zero modes

Nature Reviews Materials, 2021
Among the major avenues that are being pursued for realizing quantum bits, the Majorana-based approach has been the most recent to be launched. It attempts to realize qubits that store quantum information in a topologically protected manner.

Superconductivity and Hype-Superconductivity

Physics Bulletin, 1987
There's never been quite the media coverage for solid state physics that we have experienced over the past year. Of course, there is something magical about superconductivity – perpetual motion at least, if not the promise of free electricity as suggested by some of the headlines.
