Magnetism and structural distortions in the Sr(2-x)Ba(x)NiOsO6 system

DOI

The magnetism of double perovskites can be amazingly sensitive to subtle distortions of their structures. Previous studies have shown that Ca2NiOsO6 is a ferrimagnet, Sr2NiOsO6 is a antiferromagnet, and Ba2NiOsO6 is a ferromagnet. This means that the magnetic coupling between nickel and osmium changes from antiparallel in Ca2NiOsO6 to parallel in Ba2NiOsO6 in response relatively minor distortion of the structure. We request neutron time to study solid solutions between Sr2NiOsO6 and Ba2NiOsO6 to understand the exceptionally strong coupling between magnetism and lattice distortions in this system.
