Description
The phase transition from the uncompensated antiferromagnetic state to a simple antiferromagnet, experimentally observed in UNi2Si2 is a subject of intensive discussion in recent few years. We present a study of initial mean-field equations of Axial-Next-Next-Neighbour Ising (ANNNI) model applied to the transition. The temperature evolution of a magnetic phase diagram within ANNNI model is presented. Results are discussed in comparison with other previous investigations of this topic. (Authors)
