Structural and magnetic properties of Co1−xFexSr2YCu2O7+δ compounds

Structural, magnetic and electrical properties of one-dimensional tetraamidatodiruthenium compounds.

The first bromo and iodo tetraamidatodiruthenium compounds of the type [Ru2X(μ-NHOCC6H4-R)4]n [X = Br, R = o-Me (1), m-Me (2), p-Me (3); X = I, R = o-Me (4), m-Me (5), p-Me (6)] have been prepared using solvothermal or microwave activation procedures. In these reactions ethanol or methanol as solvents have been used to make the synthesis procedures more environment-friendly. Solvothermal synthe...

Hydrogen in R2Fe17 intermetallic compounds: Structural, thermodynamic, and magnetic properties

Structural, Magnetic and Photocatalytic Properties of BiFeO3 Nanoparticles

Single phase BiFeO3 (BFO) nanoparticles as a visible light photocatalyst were successfully synthesized by thermal decomposition of the glyoxylate precursor. The glyoxylate precursors were formed by the redox reaction between ethylene glycol and nitrate ions. The phase evolution, structure and optical properties of BFO nanoparticles were characterized by X-ray diffraction, electron microscopy an...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Magnetic properties of RCr6Ge6 compounds

Compounds of the composition RCr6Ge6 have been prepared and investigated by X-ray diffraction. The crystal structure was identified as the MgFe6Ge6 type. The magnetic properties of the compounds have been investigated through measurements of the magnetization as a function of applied field and temperature. In the compounds with R-=Dy, Ho, Er, no indication of magnetic ordering was found for tem...
