# Comprehensive cluster-theory analysis of the magnetic structures and excitations in ${\mathrm{CoCl}}_{2}·2{\mathrm{H}}_{2}\mathrm{O}$

Jacob Larsen, Ursula B. Hansen, Jens Jensen
The magnetic properties of ${\mathrm{CoCl}}_{2}·2{\mathrm{H}}_{2}\mathrm{O}$ are analyzed in the mean-field/random-phase approximation using a basis of clusters with four spins along the $c$-axis chains of Co ions. The model gives a unifying account of the bulk properties, the spin waves, and the hi...
