Unravelling Structural, Orbital and Magnetic Complexity in the Frustrated Spinel ZnV2O4
ZnV2O4 is a frustrated spinel oxide in which antiferromagnetically coupled V3+ S = 1 ions dress a pyrochlore network of corner-sharing tetrahedra. Previous studies of polycrystalline samples of ZnV2O4 have revealed a series of magnetic and structural transitions stemming from a complex interplay between structural, orbital and magnetic orders. Single crystal samples of ZnV2O4, on the other hand, do not undergo the same series of transitions and instead retain cubic symmetry and magnetic disorder to low temperatures. We have recently developed a rapid microwave-assisted preparation of polycrystalline ZnV2O4, for which magnetic susceptibility data indicate an absence of long-range magnetic order and the onset of a spin glass-like state at 10 K. Here, we seek to identify the short-range magnetic correlations that stabilise this state by measurement and analysis of the diffuse magnetic scattering from our samples of ZnV2O4.
