Abstract We point out the existence of first-order phase transitions in a family of one-dimensional classical spin systems. The relevant features of such models are that they involve only local (but complex) interactions and that the corresponding transfer matrices are self-adjoint operators. Moreover, for a wide range of coupling parameters the models satisfy the reflection positivity condition. The generalization for continuous spin systems enjoys similar properties.
