(a) X-ray diffractogram of a film on YSZ(111) substrate. (b) Azimuthal scans of the reflection for two films, with the upper one shifted for clarity.
SHG spectra of a -oriented epitaxial film recorded at with light incident under an angle of to the film plane. The inset details the geometry of the experiment. The and polarizations are oriented parallel to the axis and in the plane, respectively.
Polarization dependence of the SHG (see text) in a film recorded at with light incident under a small angle with the axis.
(a) Temperature-dependent inverse susceptibility of a sample recorded in the indicated magnetic fields along the axis and in the plane. (b) Magnetization anomalies below observed for several films. The thicknesses in nm are given in the plot. The dashed lines indicate that the low-temperature phase transitions are independent of film thickness. (c) Normalized difference in magnetization between temperature increasing and decreasing runs at .
Magnetization vs increasing and decreasing magnetic fields applied along the axis and in the plane of a film at . Inset: Derivative revealing the hysteretic transition to the high-field phase (see text).
