چکیده

The combined local structure techniques, extended x-ray absorption fine structure and neutron pair distribution function analysis, have been used for temperatures 4< or =T< or =330 K to rule out a large Jahn-Teller (JT) distortion of the Co-O bond in La1-xSrxCoO3 for a significant fraction of Co sites (x< or =0.35), indicating few, if any, JT-active, singly occupied e_{g} Co sites exist.

Magnetization reversal and nanoscopic magnetic-phase separation in La1−xSrxCoO3

The doped perovskite cobaltite La1−xSrxCoO3 LSCO has been advanced as a model system for studying intrinsic magnetic phase separation. We have employed a first-order reversal curve FORC method to probe the amount of irreversible switching in bulk polycrystalline LSCO as a function of Sr doping, field cooling procedure, and temperature. The value of the FORC distribution is used as a measure of ...

Structure of CaMnO3 in the range 10KpTp550K from neutron time-of-flight total scattering

The local and average structure of the Ca endmember of the La1 xCaxMnO3 series has been investigated. Neutron powder diffraction-based high real-space resolution atomic pair distribution function (PDF) analysis, yielding the local atomic structure, and the corresponding Rietveld analysis yielding the average crystal structure show that the two structural scales are in accord in this material, a...

Understanding the insulating phase in colossal magnetoresistance manganites: shortening of the Jahn-Teller long-bond across the phase diagram of La1-xCaxMnO3.

The detailed evolution of the magnitude of the local Jahn-Teller (JT) distortion in La(1-x)Ca(x)MnO3 is obtained across the phase diagram for 0< or =x< or =0.5 from high-quality neutron diffraction data using the atomic pair distribution function method. A local JT distortion is observed in the insulating phase for all Ca concentrations studied. However, in contrast with earlier local structure...

Sensing properties of perovskite oxide La1-xSrxCoO3-δ obtained by using pulsed laser deposition

La1-xSrxCoO3-δ belongs to the group of perovskite oxides of the ABO3 structure, with a trivalent rare earth in the A position (La) and a trivalent metal ion in the B position (Co). Doping with divalent Srions at the trivalent La-positions creates oxygen vacancies which give the oxide catalytic properties to H2O2. However, the conventional techniques which are used to prepare this oxide such as ...
