(a) The crystal quality of epitaxial Sr₂IrO₄ film on SrTiO₃:Nb (001) is shown by the full-width at half-maximum of (0 0 12) x-ray rocking curve. (b) Temperature dependence of the resistivity of Sr₂IrO₄ epitaxial films on SrTiO₃ and SrTiO₃:Nb substrates, the inset shows ln ρ versus T^−1/4. (c) The field cool and zero-field cool curves and the inset shows the hysteresis loops of epitaxial Sr₂IrO₄ film at 5 K and 20 K, respectively.
