“…[16][17][18] Transmission electron microscopy studies demonstrate that pulsed laser deposited SrRuO 3 thin-films can possess coherent and chemically abrupt interfaces with an underlying oxide substrate. 19,20 In short, the SrRuO 3 /SrTiO 3 system possesses a model interface.…”

We report the results of time-domain thermoreflectance (TDTR) measurements of two strongly bonded metal-oxide systems with unusually large thermal conductances. We find that TDTR data for epitaxial SrRuO 3 /SrTiO 3 interface is consistent with an interface conductance G > 0.8 GW m -2 K -1. For an Al/MgO interface at a pressure of 60 GPa, we findBoth are within 40% of the maximum possible conductance for these systems, as predicted by simple theory.

“…Perovskite-like doped lanthanum manganite La 0.67 Sr 0.33 MnO 3 (LSMO) is a half-metallic material as its Curie temperature is higher than room temperature, which is very attractive for spintronics applications, e.g. ferroelectric tunnel junctions and all-oxide magneto-electric tunnel junction with LSMO films used as ferromagnetic electrodes [1][2][3][4][5]. Recently many reports focus on the interface structural and magnetic properties of LSMO films deposited on SrTiO 3 (STO) substrates [6][7][8].…”

La 0.67 Sr 0.33 MnO 3 (LSMO) films were prepared on SrTiO 3 single-crystal substrates by the pulsed laser deposition method. X-ray photoelectron spectra (XPS) were measured for the LSMO films as-prepared, annealed in oxygen and in vacuum, respectively. Multiple peaks fitting for Mn 2p 3/2 XPS spectra shows that Mn 2+ appears and the ratio of Mn 3+ /Mn 4+ increases on the surface of LSMO film annealed in vacuum comparing with the as-prepared film, though the saturation magnetization (M s ) changes little. Mn 6+ and Mn 7+ can be detected while Mn 4+ decreases much on the surface of LSMO film annealed in oxygen. The change of Mn 3+ /Mn 4+ results in the obviously reduce of M s . O1s spectra show the gradual changes of Mn-O, Sr-O and La-O. Analysis indicates that Mn 2+ forms at the surface defects of LSMO films. Annealing in vacuum hardly affects the magnetic property of LSMO films. But annealing in oxygen greatly changes the valence states of Mn, which weakens the magnetic property of LSMO films.
