abstract Magnetic properties of the high-pressure stabilized perovskite BiFe1-yScyO3 phases (0.1 <= y <= 0.9) have been studied by means of magnetization measurements and neutron diffraction. The metastable perovskites of this series undergo irreversible polymorphic transformations upon annealing, the phenomenon referred to as conversion polymorphism. It has been found that the solid solutions with y >= 0.70 exhibit no long-range magnetic ordering regardless of their polymorph modification, while those with y <= 0.60 are all antiferromagnets. Depending on the scandium content, temperature and structural distortions, three types of the antiferromagnetic orderings, involving collinear, canted and cycloidal spin arrangements, have been revealed in the phases obtained via conversion polymorphism and the corresponding magnetic phase diagram has been suggested.
