Electron Paramagnetic Resonance of Cu Doped Na2HAs04-7H20 Single Crystals
نویسنده
چکیده
The electron paramagnetic resonance spectra of Cu doped Na 2 HAs0 4 -7H 2 0 single crystals were studied at room temperature. The results indicate the substitutional entrance of Cu in two magnetically inequivalent Na sites. Charge compensation is supposed to be fulfilled by proton vacancies. The spin Hamiltonian parameters were determined. The ground state for Cu seems to indicate the dominance of the dz2 orbital and therefore a compression of the distorted octahedron along its C4v axis.

متن کاملElectron Spin Resonance of Ni-doped CuGeO3 in the paramagnetic, spin-Peierls and antiferromagnetic states: Comparison with non-magnetic impurities
We have performed Electron Spin Resonance measurements on single crystals of the doped spin-Peierls compounds CuGe1−ySiyO3 and Cu1−xMxGeO3 with M = Zn, Mg, Ni (x, y ≤ 0.1). The first part of our experiments was performed in the paramagnetic and spin-Peierls phases at 9.5, 95 and 190 GHz. All non-magnetic impurities (Si, Zn and Mg) were found to hardly affect the position and linewidth of the si...

Single crystals of one mole % Mn doped CuGaS2 (CGS) compound semiconductor were grown by a chemical vapor transport (CVT) technique in a closed system using iodine as a transporting agent. The electron paramagnetic resonance (EPR) of the Mn ions in a CGS single crystal has been studied with an X-band spectrometer recorded at 80 K. The spectroscopic splitting tensor (g), hyperfine constant (A) a...
متن کاملEPR and Optical Absorption Studies of VO2+ Doped Trisodium Citrate Dihydrate Single Crystals
The electron paramagnetic resonance of VO2+ doped trisodium citrate dihydrate (Na3C6H5O7·2H2O) single crystals and powder has been examined at room temperature. The angular variation of the EPR spectra has shown that two different VO2+ complexes are located in different chemical environments, each environment containing two magnetically inequivalent VO2+ sites in distinct orientations occupying...

To investigation non-bonded interaction of the [CuF4]2- complex inside nanoring, we focus on the single wall boron-nitride B18N18 nanoring. Thus, the geometry of B18N18 nanoring has been optimized by B3LYP method with EPR-II basis set and geometry of the [CuF4]2- complex has been optimized at B3LYP method with Def2-TZVP basis set and Stuttgart RSC 1997 Effective Core Potential. Also electronic ...
