We report 121/123 Sb nuclear quadrupole resonance (NQR) and 51 V nuclear magnetic
resonance (NMR) measurements on kagome metal CsV 3 Sb 5 with T c= 2.5 K. Both 51 V …

The discovery of new extended structures has often led to the development of new fields in
chemistry and physics. However, the numerous combinations of metals (or cations) to yield …

Clarifying the interplay between charge-density waves (CDWs) and superconductivity is
important in the kagome metal CsV3Sb5, and pressure (P) can play a crucial role. Here, we …

Isotope Sb 121, 123 nuclei with large electric quadrupole moments are applied to
investigate the dynamics of orbital degrees of freedom in Sb-substituted iron (Fe)-based …

Spin-driven nematicity, or the breaking of the point-group symmetry of the lattice without long-
range magnetic order, is clearly quite important in iron-based superconductors. From a …

We report on the synthesis and the physical properties of Ba 1− x Rb x Ti 2 Sb 2 O (x≤ 0.4)
