abstract = {Double perovskites (DP, A2BB’O6) exhibit a breadth of
multifunctional properties with a huge potential range of
applications, including magneto-optic and spintronic
devices. However, spontaneous cation ordering is limited by
the similar size and charge of B and B’ cations. We
introduce a route to stimulate B-site rock-salt ordering. By
growing thin films on (111)-oriented substrates,
‘in-plane’ strain acts on the intrinsically tilted
oxygen octahedra of the DP and produces two different B-site
cages (in size and shape), stimulating spontaneous cation
ordering. For the ferromagnetic insulator La2CoMnO6, clear
Co/Mn ordering was achieved by growing on (111)-oriented
substrates. The difference in B-site cages was further
enhanced when grown under minor (111) in-plane compressive
strain, resulting in long-range ordering with a saturation
magnetization of 5.8 μB/formula unit (f.u.), close to the
theoretical 6 μB/f.u., without antiferromagnetic behavior.
Our approach enables the study of many new ordered DPs which
have never been made before.},
