Effect of doping on the ground-state spin of stacked organometallic ferromagnets

The effective Hamiltonians that describe the low-lying energy states of some stacked organometallic ferromagnets with dopants have been derived. It is shown that the lattice stack with N unit cells and p conduction electrons has the ground-state spin S-0 = (N + p)/2 at p < N and S-0 less than or equal to (3N - p)/2 at N less than or equal to p < 2N. This means that the ferromagnetic ground state of metallocene-based donor-acceptor stack is unstable to the donor doping and is stable to the acceptor doping. (C) 1999 John Wiley & Sons, Inc.


Effect of N-methylimidazole and 3,5-dimethylpyrazole ligands on the polymerization of di(2,6-dichlorophenolato) Cu(II)/Co(II) complexes in the solid state
Baştürkmen, M.; Hacaloğlu, Jale; Kisakürek, D. (2004-03-15)
The polymerization of 2,6-dichlorophenol (DCPH) was achieved through the thermal decomposition of copper complexes of DCPH with N-methylimidazole (NMIz) and 3,5-dimethylpyrazole (DMPz) ligands. Fourier transform infrared (FTIR), differential scanning calorimetry (DSC), mass spectrometry, ultraviolet-visible spectroscopy, diffuse reflectance spectroscopy, magnetic susceptibility balance, electron spin resonance, X-ray analysis, and elemental analysis were used to characterize the complexes. The polymerizatio...
Effect of TiO2 addition on the crystallization and tribological properties of MgO-CaO-SiO2-F2O5-F glasses
Park, Jongee; Öztürk, Abdullah (2008-04-10)
The kinetic parameters including the activation energy for crystallization (E), the Avrami parameter (n) and frequency factor (v) of a glass in the MgO-CaO-SiO2-P2O5-F system were studied using non-isothermal differential thermal analysis (DTA) with regard to small amount of TiO2 additions. It has been shown that the role of TiO2 changes from a glass network former to a glass network modifier with increasing TiO2 content in this system. The kinetic parameters of the crystallizing phases, apatite and wollast...
Effects of surface potential fluctuations on DLTS of MOS structure
Ozder, S; Atilgan, I; Katircioglu, B (1996-02-01)
Although the conventional large signal deep-level transient spectroscopy (DLTS) technique is immune to surface potential fluctuations resulting from interface charge inhomogeneities in a MOS structure, in energy resolved, small signal DLTS, the eventual surface potential fluctuation should be considered. In this paper, the effect of the potential fluctuation on the temperature-scan DLTS signal for a given gate bias has been carried out. In fact, this effect shifts the DLTS peak position to lower temperature...
Synthesis, characterization, and polymerization of polyether bridged thiophene and aniline derivatives
Tirkeş, Seha; Önal, Ahmet Muhtar; Department of Polymer Science and Technology (2008)
New compounds consisting of 3-thienyl and aniline units linked by polyether bridges have been synthesized and their electrochemical polymerization was performed via constant potential electrolysis and cyclic voltammetry. In the case of 3-thienyl derivatives two compounds, 1,12-di-3-thienyl-2,5,8,11-tetraoxadodecane (MI) and 1,15-di-3-thienyl-2,5,8,11,14-pentaoxapentadecane (MII) were synthesized utilizing literature methods and their corresponding polymers, poly(I) and poly(II) were prepared in an electroly...
Effect of polymer additives on the physical properties of bitumen based composites
Doğan, Mehmet; Bayramlı, Erdal; Department of Polymer Science and Technology (2006)
Polymer modified bitumen is a binder obtained by the incorporation of various types of polymers in bitumen using mechanical mixing or chemical reactions. There are several factors affecting the properties of polymer modified bituminous composites such as; chemical composition of bitumen, kind of polymer and filler, compatibility of bitumen and polymer, amount of bitumen, polymer and filler, particle size of filler and process conditions. The main objective of this study is to determine the effects of polyme...
