A magnetic excitation linking quasi-1D Chevrel-type selenide and arsenide superconductors

Logan M. Whitt, Tyra C. Douglas, Songxue Chi +2

The quasi-one-dimensional Chevrel phases, A $_{2}$ Mo $_{6}$ Se $_{6}$ (A = Tl, In, K, Rb, Cs), are of interest due to their atypical electronic properties. The Tl and In analogues undergo a…
