Thermal expansionc oefficient of Ln0.6Sr0.4Co0.2M0.8O3−δ (Ln=La,Nd,Sm and M=Fe,Ni,Mn) perovskite oxide
Authors
Abstract:
In this study, Thermal expansion coefficient (TEC) variation of Ln0.6Sr0.4Co0.2M0.8O3−δ (Ln=La,Nd,Sm and M= Fe,Ni,Mn) perovskite oxide have been evalouated. Different compounds have been prepared and thermal expansion coefficient have been meseaured in different temperature by means of dilatometer analysis. Structural parameters of compounds have been determined by X-ray diffraction and Field Emission Scanning Electron Microscopy (FE-SEM) has been used for the morphological study. Experimental results have shown TEC decreases favorably with substitution of Nd3+ and Mn3+ ions in the lattice

Self-templated synthesis and thermal conductivity investigation for ultrathin perovskite oxide nanowires.
The large thermal conductivity of bulk complex metal oxides such as SrTiO(3), NaCo(2)O(4), and Ca(3)Co(4)O(9) has set a barrier for the improvement of thermoelectric figure of merit and the applications of these materials in high temperature (≥1000 K) thermoelectric energy harvesting and solid-state cooling. Here, we present a self-templated synthesis approach to grow ultrathin SrTiO(3) nanowir...
full textThermal equation of state of CaGeO3 perovskite
Pressure-volume-temperature data have been obtained for CaGeO3 perovskite up to 9.6 GPa and 1100 K using a cubic anvil, DIA-type high-pressure apparatus in conjunction with synchrotron X-ray diffraction. The data were analyzed using Birch-Murnaghan equation of state and thermal pressure approach with the bulk modulus at ambient pressure, KT0, and its pressure derivative, K′ T0, constrained by p...

We have fabricated perovskite superlattices consisting of two ferromagnetic metallic oxides: La0.67Ca0.33MnO3 ~LCMO! and SrRuO3 ~SRO!. We have investigated the magnetotransport and magnetic properties of a series of samples, in which the layer thickness of LCMO is fixed and that of SRO varied from 0 to 20 unit cells. The magnetoresistance ratio in a superlattice can be increased by a factor of ...

We report a combined high-temperature scanning tunneling microscopy, ion scattering spectroscopy, and photoelectron spectroscopy study of bare lanthanum aluminate LaAlO3 LAO and of the initial stages of anatase TiO2 growth on LAO 001 . LAO 001 exhibits mixed La–O and Al–O2 surface terminations at 400 °C. Heteroepitaxial TiO2, grown by evaporating Ti metal in O2, nucleates near step edges, growi...
