2-(methylamino) pyridine (hmap) reacts with meli in thf and generates the lithium salt (limap). further reaction of [cu(tmeds)2][cucl2] (tmeda=tetramethylethylenediamine) with one equivalent of this ligand in thf leads to the formation of a yellow dimeric cu(i) complex, [cu(map)]2. analytical data, molecular weight, and magnetic susceptibility measurements, confirm the formula [cu(map)]2 .

In this research, M- type strontium hexaferrite nanoparticles (SrFe12O19) were synthesized via combustion sol–gel technique. To determine the optimum annealing temperature, thermogravimetry-differential thermal analysis (DTA/TG) was used.  Based on the results obtained from this analysis, the powders strontium hexaferrite were annealed between temperatures 750 and 1050°C. The structural and mor...

Single phase Eu doped GdMnO3 ceramics were prepared using solid state reaction route. Several different characterization techniques were used to investigate the structural and magnetic properties of the samples, including X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDX) and Vibrating Sample Magnetometer (VSM). All samples indicated single p...

The macrocyclic complexes of biological importance with power transition metals are synthesized by template methodology leading to the formation of the complex [MLX] X2; where L is macrocyclic ligand derived from 3,4-diaminotoluene, 2,4-thiazolidinedione, M=Cr (III) and Fe(III) X is Cl-, CH3COO- or NO3_.Characterisation of these complexes are through with the assistance of elemental analyses(CH...

  The granular Gd1-x-zPrxCazBa2Cu3O7-δ high-temperature cuprate samples with 0.0 ≤ x ≤ 0.3 and 0.0≤ x ≤ 0.35 are prepared by standard solid state reaction and characterized by XRD and SEM techniques. The BaCuO2 and impurity phases are less than 1% in the samples having high levels of pr and Ca concentrations. The electrical resistivity measurements show a nonlinear reduction in Tc(x,z=etc) vers...

Ferromagnetic nanowires showed solitary and tunable magnetization properties due to their inherent shape anisotropy. The fabrication of such nanowires in polycarbonate track-etched and anodic alumina membranes have been widely studied during the last 15 years [1-2]. Their potential applications might be explored in spintronic devices and more specifically in magnetic random access memory (MRAM)...
