Query: Spin ordering and electronic texture in the bilayer iridate
  Sr$_3$Ir$_2$O$_7$   Through a neutron scattering, charge transport, and magnetization study, the
correlated ground state in the bilayer iridium oxide Sr$_3$Ir$_2$O$_7$ is
explored. Our combined results resolve scattering consistent with a high
temperature magnetic phase that persists above 600 K, reorients at the
previously defined $T_{AF}=280$ K, and coexists with an electronic ground state
whose phase behavior suggests the formation of a fluctuating charge or orbital
phase that freezes below $T^{*}\approx70$ K. Our study provides a window into
the emergence of multiple electronic order parameters near the boundary of the
metal to insulator phase transition of the 5d $J_{eff}=1/2$ Mott phase.
