AB We demonstrate that the gauged BPS baby Skyrme model with a doublevacuum potential allows for phase transitions from a non-solitonic to a solitonic phase,where the latter corresponds to a ferromagnetic liquid. Such a transition can be generatedby increasing the external pressure P or by turning on an external magnetic field H.As a consequence, the topological phase where gauged BPS baby skyrmions exist, is ahigher density phase. For smaller densities, obtained for smaller values of P and H, aphase without solitons is reached. We find the critical line in the P,H parameter space.Furthermore, in the soliton phase, we find the equation of state for the baby skyrmionmatter V = V (P,H) at zero temperature, where V is the “volume”, i.e., area of thesolitons
