      abstract     = {5d iridium oxides are of huge interest due to the potential
                      for new quantum states driven by strong spin-orbit coupling.
                      The strontium iridate Sr2IrO4is particularly in the
                      spotlight because of the so-called jeff=1/2 state consisting
                      of a quantum superposition of the three local t2g orbitals
                      with, in its simplest version, nearly equal populations,
                      which stabilizes an unconventional Mott insulating state.
                      Here, we reportan anisotropic and aspherical magnetization
                      density distribution measured by polarized neutron
                      diffractionin a magnetic field up to 5 T at 4 K, which
                      strongly deviates from a local jeff=1/2 picture even when
                      distortion-induced deviations from the equal weights of the
                      orbital populations are taken into account. Once
                      reconstructed by the maximum entropy method and multipole
                      expansion model refinement, the magnetization density shows
                      four cross-shaped positive lobes along the crystallographic
                      tetragonal axes with a large spatial extent, showing that
                      the xy-orbital contribution is dominant.The analogy to the
                      superconducting copper oxide systems might then be weaker
                      than commonly thought.},
