TL;DR: This work reports the unprecedented enhancement of a superconducting instability by disorder in single crystals of Na2−δMo6Se6, a q1D superconductor comprising MoSe chains weakly coupled by Na atoms and argues that disorder-enhanced Coulomb pair-breaking may be averted due to a screened long-range Coulomb repulsion intrinsic to disordered q1d materials.

TL;DR: The ternary molybdenum chalcogenides have played a major role in superconductivity: opening of the teranary superconductor range, competition between superconductivities and magnetism as mentioned in this paper.

TL;DR: In this article, the reduced compound YBa 2 Cu 3 O 6 is found to order antiferromagneticnetically belowT N = 420 ± 10K, and the magnetic moment is about 0.6 ± 0.05 μ B on the Cu 2+ sites and aligned perpendicular to the tetragonal caxis.

TL;DR: In this paper, the first specific-heat measurements in the normal and superconducting states of quasi-one-dimensional (QoE) superconductors were presented, and the authors showed that the absence of any metal-insulator transition in these materials is due to a larger in-plane bandwidth, leading to increased interchain hopping which suppresses the density wave instability.

TL;DR: In this article, the p-type conduction properties of polycrystalline Mo9 cluster chalcogenides AgxMo9Se11 (3.4≤x≤3.9) have been determined in the 300-800 K temperature range.
