Typical XRD pattern of a PNMO film grown at under 900 mTorr. The inset shows a rocking curve recorded on the (002) reflections.
M-T curve measured in 500 Oe applied magnetic field for a PNMO film grown at and 900 mTorr. top inset presents corresponding M-H loop measured at 10 K and bottom inset presents the dM/dT vs temperature curve. The position of the magnetic transition points are marked by arrows.
(a) Polarization dependence of Raman scattering spectra of a PNMO film grown at and 900 mTorr. The inset presents a schematic of the polarization configurations used to measure the Raman spectra of our films. (b) Temperature dependence of Raman spectra measured in the XX configuration.
Temperature dependence of the octahedra stretching mode in the epitaxial film and the corresponding mode in a polycrystalline bulk sample. Arrow shows the softening temperature.
