      abstract     = {La0.4Na0.6Fe2As2 single crystals have been grown out of an
                      NaAs flux in an alumina crucible and characterized by
                      measuring magnetic susceptibility, electrical resistivity,
                      specific heat, as well as single-crystal x-ray and neutron
                      diffraction. La0.4Na0.6Fe2As2 single crystals show a
                      structural phase transition from a high-temperature
                      tetragonal phase to a low-temperature orthorhombic phase at
                      Ts=125 K. This structural transition is accompanied by an
                      anomaly in the temperature dependence of electrical
                      resistivity, anisotropic magnetic susceptibility, and
                      specific heat. Concomitant with the structural phase
                      transition, the Fe moments order along the a direction with
                      an ordered moment of 0.7(1) μB at T=5 K. The
                      low-temperature stripe antiferromagnetic structure is the
                      same as that in other AFe2As2 (A = Ca, Sr, Ba) compounds.
                      La0.5−xNa0.5+xFe2As2 provides a material platform for the
                      study of iron-based superconductors where the electron-hole
                      asymmetry could be studied by simply varying the La/Na
                      ratio.},
