Abstract

This brief outlook is inspired by pioneering works by V.V. Eremenko with co-authors on the first observations of similarities in the low-temperature phase formation of conventional antiferromagnets and superconductors in the of vicinity critical temperature. To extend such an analogy, the temperature dependences of magnetic and structure properties are compared for anisotropic superconductors and antiferromagnets, featured by competing orders parameters (multiferroics). The deserved common features of their critical behavior in the neighbourhood of ordering temperature Tc are discussed.

PACS: 64.75.–g Phase equilibria.

Key words: diselenide Nb, anion-excess manganites, competiting interactions, critical indexes.
