For the compositions with <em>y<\/em> \u2265 0.2, the perovskite phases can only be stabilized under high-pressure conditions and the metastable phases were subject to post-synthesis thermal treatment. As a result, we observed a set of annealing-stimulated irreversible phase transformations between the different metastable perovskite phases. This remarkable behaviour allowed us to obtain these perovskites at ambient conditions in different polymorphs, which represent novel structures with interesting magnetic properties. In particular, a new orthorhombic modification of BiScO<sub>3<\/sub> has been obtained and a novel magnetic phase transition from an unusual collinear magnetic ground state to a cycloidal structure has been found in the converted polar <em>R3c<\/em> modification of the BiFe<sub>0.7<\/sub>Sc<sub>0.3<\/sub>O<sub>3<\/sub> composition.<\/p>\n<p style=\"text-align: justify;\">We refer to the annealing-stimulated irreversible transformations as \u2018\u2018conversion polymorphism\u2019\u2019 and demonstrate that this is a rather general phenomenon, which has been likely overlooked in many other metastable phases.
