ساخت نانو بلورک‌های δ-7O3Cu2YBa به روش مکانوشیمیایی و بررسی دمای گذار ترکیبات -7O3Cu2YBa(x-1) + 2 xMnO (02/0 ،015/0 ،01/0 ،005/0 ،0 = x)
In this research, YBa2Cu3O7-d (0 < d < 1) nanocrystalite superconductor was prepared by mechanochemical alloying method. We synthesized YBa2Cu3O7-d via mixing the BaCO3, Y2O3, CuO powders and milling in SPEX 8000 for 5h with weight ratio of ball to powder 10:1 and steel balls of 11mm diameter, followed by heating for 4h at 850 ˚C. The superconductor phase formation process was completed with si...
متن کاملRaman scattering study of Nd 1 − x Sr x MnO 3 ( x = 0 . 3 , 0 . 5 )
We report on polarized Raman scattering of single crystals of Nd1−x SrxMnO3 (x = 0.3, 0.5). Raman spectra of Nd0.7Sr0.3MnO3 show a significant change through the metal–insulator transition. In the ferromagnetic metallic phase phonon modes grow in intensity and number while the electronic continuum becomes more pronounced. We suggest that these effects are due to the strong competition between t...
متن کاملTransport properties in La 0 . 7 − x Gd x Sr 0 . 3 MnO 3 system
The influence of Gd doping at La-site on the electrical transport properties and the colossal magnetoresistance of La0.7−xGdxSr0.3MnO3 (x = 0.00, 0.10, 0.15, 0.20, 0.30, 0.40, 0.50, 0.60, and 0.70) is studied. The experimental results indicate that the transport properties exhibit abnormal behavior under high doping condition. For x = 0.50, we find that a transition from metal to insulator occu...
متن کاملX-ray peak broadening analysis in LaMnO3+δ nano-particles with rhombohedral crystal structure
In this work, structural and magnetic properties of LaMnO3+δ compound prepared by citrate precursor method and annealed in presence of oxygen are investigated. The structural characterization of LaMnO3+δ by X-ray powder diffraction and using X’pert package and Fullprof program is evidence for a rhombohedral structure (R-3c space group) confirmed by FTIR measurement. The magnetic measurements sh...
متن کاملX-Ray, Crystal Structure and Solution Phase Studies of a Polymeric SrII Compound
In the crystal structure of the title polymeric compound, [C42H38N6O33Sr5.2(H2O)]n, five independent metal atoms (Sr1-Sr5) have different coordination environments. The Sr1 and Sr5 atoms are nine coordinated and feature distorted tricapped trigonal-prismatic and capped square-antiprismatic geometries, respectively....
