The ability to host five or more cations on a sublattice within a single crystal oxide offers new opportunities to design materials with tailored bonding environments and functional properties. La(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3, which straddles the phase-boundary between orthorhombic and rhombohedral, is expected to exhibit a tremendous level of local distortion. Despite this, La(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 is found to exhibit a surprisingly well-ordered lattice, which homogeneously favors the orthorhombic phase. The observation of long-range order that emerges out of a configurationally complex local bonding environment suggests unforeseen cooperative effects at play in entropy stabilized materials.
