What High Pressure Studies Have Taught Us About High-Temperature Superconductivity

چکیده

Superconductivity is an important area of modern research which has benefited enormously from experiments under high pressure conditions. The focus of this paper will be on three classes of high-temperature superconductors: (1) the new binary compound MgB2, (2) the alkali-doped fullerenes, and (3) the cuprate oxides. We will discuss results from experiment and theory which illustrate the kinds of vital information the high-pressure variable can give to help better understand these fascinating materials.

Substitution of TMTSeF with TMTTF in (TMTSeF)2ClO4 : high pressure studies

2014 [(TMTSeF)1-x(TMTTF)x]2ClO4 alloys have been studied under pressure for pressures up to 18 kbar through resistivity measurements. On substitution of TMTSeF in the superconducting compound (TMTSeF)2ClO4 with TMTTF a low temperature metal-insulator (M-I) transition is found at ambient pressure; above some critical pressure, Pc, the M-I transition is suppressed giving rise to a metallic state ...

The Next Breakthrough in Phonon-Mediated Superconductivity

If history teaches us anything, it is that the next breakthrough in superconductivity will not be the result of surveying the history of past breakthroughs, as they have almost always been a matter of serendipity resulting from undirected exploration into new materials. Still, there is reason to reflect on recent advances, work toward higher Tc of even an incremental nature, and recognize that ...

Inverse correlation between quasiparticle mass and T c in a cuprate high-T c superconductor.

Close to a zero-temperature transition between ordered and disordered electronic phases, quantum fluctuations can lead to a strong enhancement of electron mass and to the emergence of competing phases such as superconductivity. A correlation between the existence of such a quantum phase transition and superconductivity is quite well established in some heavy fermion and iron-based superconducto...

Dome-shaped magnetic order competing with high-temperature superconductivity at high pressures in FeSe

The coexistence and competition between superconductivity and electronic orders, such as spin or charge density waves, have been a central issue in high transition-temperature (Tc) superconductors. Unlike other iron-based superconductors, FeSe exhibits nematic ordering without magnetism whose relationship with its superconductivity remains unclear. Moreover, a pressure-induced fourfold increase...

Superconductivity in the polymeric phase of Na2CsC60

We have studied the reversible pressure induced structural transition (primitive cubic to polymeric monoclinic) of Na2CsCGoand the superconductivity in both phases. We have established that the polymeric phase of Na2CsC60 is superconducting with an ambient pressure transition temperature about 3 K lower than that for the primitive cubic phase. We believe that an analogous lowering of the transi...
