Abstract: The present work aims to describe, within a single phenomenological approach,the specific sequence of phase transitions observed in the rare-earthmanganites RMnO3 at zero magnetic field. It is shown that a single integrateddescription of the temperature versus composition phase diagrams of thesecompounds and related solid solutions can be obtained within the scope ofLandau theory by adopting the so called type-II description of the modulatedphases.
