Signatures of superconductivity near 80 K in a nickelate under high pressure

Nature, 2023
Although high-transition-temperature (high- T _c) superconductivity in cuprates has been known for more than three decades, the underlying mechanism remains unknown^ 1 – 4 .

Superconductivity in pressurized trilayer La4Ni3O10−δ single crystals

Nature, 2023
The pursuit of discovering new high-temperature superconductors that diverge from the copper-based model1–3 has profound implications for explaining mechanisms behind superconductivity and may also enable new applications4–8. Here our investigation shows

Superconductivity

Science, 1964
The number of superconductors known in 1935 was about 80, in 1950 over 100, and when last counted more than 900. Though the growth of a field cannot be measured by a single index, these numbers symbolize what has happened to the science of superconductivity; a sequence of discoveries has steadily enlarged the scope and importance of the subject.

Possible High T_{c} Superconductivity in La_{3}Ni_{2}O_{7} under High Pressure through Manifestation of a Nearly Half-Filled Bilayer Hubbard Model.

Physical Review Letters, 2023
Inspired by a recent experiment showing that La_{3}Ni_{2}O_{7} exhibits high T_{c} superconductivity under high pressure, we theoretically revisit the possibility of superconductivity in this material. We find that superconductivity can take place, which

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

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 ...

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.

Ambient-pressure superconductivity onset above 40 K in (La,Pr)3Ni2O7 films

Nature
The discovery of Ruddlesden–Popper (RP) bilayer nickelate superconductors under high pressure has opened a new chapter in high-transition-temperature superconductivity1, 2, 3, 4, 5, 6, 7–8.

Superconductivity and Ferromagnetism

IBM Journal of Research and Development, 1962
Superconductivity and ferromagnetism were considered exclusive phenomena for many decades. Ever since Kamerlingh Onnes' discovery that strong magnetic fields will destroy superconductivity it had been assumed that the large internal, or Weiss field, in a ferromagnet would never permit the occurrence of superconductivity.

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.
