• A one-dimensional Ising chain with spin-lattice coupling is considered. If the latticeis harmonic but has no translational symmetry, there appears effectively through thespin-lattice coupling a four-spin interaction which decays exponentially withdistance. It is shown rigorously that this spin system in the ground state exhibits adevil's staircase as a function of the exchange parameter J because of the long rangeinteraction. The ground state phase diagram of the spin system under an externalmagnetic field is speculated.
