Thin films of perovskite manganite La0.7Ca0.3MnO3 were grown epitaxially on various substrates by either the pulsed laser deposition method or laser molecular beam epitaxy. The substrates change both the volume and symmetry of the unit cell of the films. It is revealed that the symmetry as well as the volume of the unit cell have strong influence on the metal-insulator transition temperature an...

Solid solutions involving natural Mn3+O(OH) polymorphs, groutite, manganite, and feitknechtite are characterized discussed based on original literature data the chemical composition, powder single-crystal X-ray diffraction, middle-range IR absorption spectra of these minerals. It is shown that manganite forms two kinds solid-solution series, in which intermediate members have general formulae (...

This study was conducted to investigate the use of cubic LaMnO3 nano-perovskite as a green catalyst for the degradation of an aqueous solution of methyl orange under different conditions. Nanoscale cubic lanthanum manganite with the particle size of ~20 nm was successfully synthesized via citrate sol-gel method. The sample was characterized using the FT-IR and UV-Vis spectroscopy, XRD, SEM, and...

Complexions at the Electrolyte/Electrode Interface In article number 2100967, Thomas Götsch and co-workers reveal that a complexion is formed between yttria-stabilized zirconia electrolyte lanthanum strontium manganite air electrode during sintering process of solid oxide cells. This nanometer-wide interlayer self-limited width characterized by partial amorphization compositional gradients. It ...

MicroElectroMechanical Systems (MEMS) made of heterostructures of crystalline oxide materials with targeted physical properties may be applied as sensors having different integrated functionalities. In this work, we explore the feasibility of manganite thin film based epitaxial MEMS for thermometric micromechanical sensing. We investigate the mechanical properties of La1−xSrxMnO3, with x ≈ 1/3,...

We review recent experimental work falling under the broad classification of colossal magnetoresistance (CMR), which is magnetoresistance associated with a ferromagnetic-toparamagnetic phase transition. The prototypical CMR compound is derived from the parent compound, perovskite LaMnO3. When hole doped at a concentration of 20–40% holes/Mn ion, for instance by Ca or Sr substitution for La, the...
