Abstract
A linear array of coupled spins is shown under appropriate conditions to be unstable with respect to alternation of the lattice parameter much like the Peierls instability of a one‐dimensional metallic lattice. A second‐order phase transition occurs, below which transition temperature the magnetic susceptibility decreases to zero. The model is discussed with respect to the analogous physical system of solid Würster's blue perchlorate (N,N dimethyl paraphenylenediamine perchlorate) where qualitative agreement is observed.Keywords
