TL;DR: Differential susceptibility measurements were performed on a single crystal of RbCoCl3 · 2H2O and an anti-ferromagnetic ordering was found at 2.975 K.

TL;DR: In this article, the transverse susceptibility of the c-cyclic version of the one-dimensional XY model with respect to an infinitesimal magnetic field in the x-direction is investigated in more detail.
Abstract: The transverse susceptibility of the c-cyclic version of the one-dimensional XY model with respect to an infinitesimal magnetic field in the x-direction is investigated in more detail. Special attention is paid to the c-cyclic version of the one-dimensional Ising model. The c-cyclic susceptibility χxx is evaluated explicitly. The autocorrelation function of the magnetization Mx turns out to be time dependent in the c-cyclic Ising model.

TL;DR: In this article, it was shown that for alternating XY chains xzz have two singularities at different values of the applied magnetic field, i.e., the singularity at the same value of the magnetic field.
