A series of polycrystalline YMn1−xRuxO3 (0 ≤ x 0.2) samples were prepared by traditional solid-state reaction method. Effects doping on the microstructures and magnetic properties investigated. Microstructural results reveal that crystallize in a single hexagonal structure with P63cm group for 0.1. Lattice parameters a, c, unit-cell volume are found to increase content, which ascribed larger radius Ru3+ than Mn3+. Weak ferromagnetism is enhanced increasing concentration x. The bond angles...
The compressive LaMnO3+δ thin films with thickness of ∼20 nm are grown on LaAlO3 (001) single crystal substrates under various oxygen environment. With decreasing pressure, the in-plane strain is enhanced. It found that breathing mode (Q1) and basal plane distortion (Q2) MnO6 octahedron suppressed, while octahedral stretching (Q3) promoted. promoted Q3 switches orbital order from x2-1/y2-1 to (x2-y2)+(z2-1) type. ferromagnetic (FM) transition temperature Tc increases 85 K 105 low-temperature...

Hexagonal yttrium manganite (YMnO3) and chromium doped (YMn1 – xCrxO3) were prepared by the solid-state method. X-ray diffraction Raman scattering combined to explore structural characterization. Structural analysis illustrates that lattice is compressed tilt of MO5 (M = Cr or Mn) bipyramid decreased with an increase in Cr3+ concentration, leading declining frustration. Magnetic measurement suggests both weak ferromagnetic (FM) antiferromagnetic (AFM) orderings enhanced growth doping...

Epitaxial orthorhombic YMn0.9Ru0.1O3 films with different thickness have been grown on (001)-SrTiO3 substrates by pulsed laser deposition (PLD). The crystal structure is well investigated X-ray Diffraction. It found that the out-of-plane parameter c slowly increases decreasing of samples because tensile strain between and along axis. lengths in-plane Mn-O bonds expand enhancement strains, which proved Raman scatting. magnetic measurements reveal there exist two transition temperatures TN1...
With the energy consumption increasing, coal supply in China has been becoming tight, which made it difficult for thermal power generation Yunnan Province. Making full use of local inferior and biomass resources can remedy lack fuel plants. In this paper, an oxygen-rich atmosphere thermogravimetric experiment was performed a blended sample Xiaolongtan lignite, Yiliang tobacco rod, Fuyuan bituminous coal. The combustion characteristics mixed under several key operating parameters (i.e., mass...
A hexagonal crystal lattice with the perovskite structure can be treated as rhombohedral or pseudocubic structure. The publication by Sis and Wirtz [J. Appl. Phys. 44, 5553 (1973)] presented a schematic diagram to explain these relationships, but made mistake in lattice, which is corrected here.
This paper reports the effects of substrate-induced strain on high-quality La0.5-xDyxCa0.5-ySryMnO3 (0≤x≤0.2) (LDCSMO) films grown (00l) SrTiO3 (STO) substrate. LDCSMO were epitaxially STO substrate along [001] direction. The lattice parameter c film increases relatively with thickness increasing, and in-plane tensile was controlled by varying thickness. Raman results at room temperature show that Mn-O bond stretching MnO6 distortion suppressed decreasing. magnetic CO-AFM insulating phase...
Abstract Magnetism of materials may be adjusted by varying the adjacent magnetic ions in materials, such as Ru 4+ SrRuO 3 . We here report a study structure, electro-transport and properties poly-crystallized SrRu x O , which is synthesized solid-state reaction. Results show that all samples remain single phase, grain size increases with increasing content. A semiconducting behavior ≤ 1 Fermi Liquid > are observed determined. At 10 K, saturated moment from 21.02 to 29.82 (emu/g), while...
