Typical scan of . The intensities are shown on a logarithmic scale. Only (00 l) reflections can be observed which indicates a textured growth mode. No impurity phases are present. The inset shows a zoom of the (003) reflection with clear Laue oscillations.
Typical rocking curve of the (003) reflection of . Inset: RHEED pattern with beam azimuth in direction of MgO. The streaks indicate atomically smooth and epitaxial growth.
Top: Typical -scan of the (112) reflection of . Bottom: Corresponding -scan of the (111) MgO.
Resistivity vs. temperature for . The onset of is at 4.15 K and at 4.05 K (defined by the 90%/10% criterion).
Magnetization measurement of by SQUID. The inset shows an enlargement of the transition region.
