Comparative study of electrical transport and magnetic measurements of Y3Ba5Cu8O18±δ and YBa2Cu3O7−δ compounds: intragranular and intergranular superconducting properties

Analysis on the microstructure and magnetic properties of MgGaFeO4 spinel compound

“…The investigations of EDX spectrum suggest that the contents of several main elements and atomic stoichiometry for A survey of the published literature shows that process modeling of CMCs has been studied by a number of researchers. Processes that have been modeled include RMI, 15,16 CVD, 17,18 CVI, [19][20][21][22] and Sol-Gel Infiltration. 23 Impregnation of alumina matrix in eight-harness satin Nextel 610 fabric has been studied numerically in Ref.…”

[15][16][17][18] In the mixed spinel cubic structure with the space group Fd3m (No. 221), there are eight formula units for each unit cell, in which the unit cell contains 24 cations and 32 anions in the close packing structure.…”

Electrochemical and magnetic properties of electrospun SmFeO3 and SmCoO3 nanofibers

“…(1-x)BaTiO 3 /xSr 0.92 Ca 0.04 Mg 0.04 Fe 12 O 19 composite, (BaTiO 3 -SrTiO 3 )/WO 3 composite as well as SrFe 11.96 V 0.04 O 19 /Ni 0.5 Mn 0.5 Fe 2 O 4 nanocomposite, were investigated in detail. [9][10][11][12] Samarium iron oxide (SmFeO 3 ) possesses remarkable magnetic characteristics, favorable p-type semiconducting property, and outstanding gas-sensitivity. 5,6 SmFeO 3 has distorted orthorhombic structure with space group Pnma(62) and FeO 6 octahedron tilted toward Sm 3+ cation to sustain the Sm-O bonding.…”

“…In addition, the distortion of MO 6 octahedron highly affects the magnetic properties of the materials. In previous research, the magnetic and electrical behaviors of some simple and complexed perovskite oxides, such as Y 3 Ba 5 Cu 8 O 18±δ , YBa 2 Cu 3 O 7‐δ , (1‐x)BaTiO 3 /xSr 0.92 Ca 0.04 Mg 0.04 Fe 12 O 19 composite, (BaTiO 3 ‐SrTiO 3 )/WO 3 composite as well as SrFe 11.96 V 0.04 O 19 /Ni 0.5 Mn 0.5 Fe 2 O 4 nanocomposite, were investigated in detail 9–12 . Samarium iron oxide (SmFeO 3 ) possesses remarkable magnetic characteristics, favorable p‐type semiconducting property, and outstanding gas‐sensitivity 5,6 .…”
