Low-temperature ordered phases of the spin-$\frac{1}{2}$ XXZ chain system Cs${}_2$CoCl${}_4$

O. Breunig, M. Garst, A. Rosch +6

In this study the magnetic order of the spin-1/2 XXZ chain system Cs${}_2$CoCl${}_4$ in a temperature range from 50 mK to 0.5 K and in applied magnetic fields up to 3.5 T is investigat…
