Experimental measurements for the magnetization at various temperatures are analyzed using a mean field model for the purely ferromagnetic spin configuration near the metamagnetic phase transitions in La1-x Nd (x) Mn2Si2 (x=0.3) at a constant magnetic field (50 mT). By fitting the temperature dependence of the magnetization from the free energy in the mean field model to the experimental data for this compound, the coefficients in the free energy expansion are determined. Our analysis of the magnetization describes a first-order character of the metamagnetic transition in La1-x Nd (x) Mn2Si2 (x=0) on the basis of the mean field model studied here.

Analysis of Magnetization as a Function of Temperature for CoMn1-x Fe (x) Ge YÜCE EMRE, SÜHEYLA; Doğan, Ezgi; Emre, B.; Bruno, N. M.; Karaman, I.; Yurtseven, Hasan Hamit (2017-12-01) Our experimental measurements for the magnetization M as a function of temperature are analyzed for the multilayer structure of CoMn1-x Fe (x) Ge for x = 0.085 and x = 0.12 at constant magnetic fields of 3, 5, and 7 T. For this analysis, a power-law formula is used below the transition temperature T-C for these compositions and the values of the critical exponent beta for the magnetization M (order parameter) are determined. Our analysis indicates that a first order transition at lower concentrations (x = 0...
Spontaneous polarization close to phase transitions in NaNO2 Yurtseven, Hasan Hamit; Tari, O (2001-08-01) We give here the calculation of the order parameter and the spontaneous polarization as functions of temperature using the mean field model close to the phase transitions in NaNO2. We have fitted our calculated order parameter to the observed one from the literature. From this fitting, we have then calculated the spontaneous polarization as a function of temperature close to the phase transitions in NaNO2. Our calculated spontaneous polarization is in good agreement with the observed spontaneous polarizatio...
A Density Functional Study of 1, 1, 5-Tris(4-dimethylaminophenyl)-3-methyl-divinylene

Fellah, Mehmet Ferdi; Önal, Işık (2010-04-01)

The optimized molecular structural parameters and UV-vis, IR and Raman spectra of a dye molecule with an open formula of 1,1,5-Tris(4-dimethylaminophenyl)-3-methyl-divinylene are determined by means of density functional theory (DFT) calculations using B3LYP/6-31G** formalism. Neutral and cationically charged molecules are used for DFT computations. C-C, C-C, and N-C bond distances of dimethylaminophenyl groups of the dye molecule are in reasonable agreement with the experimental and theoretical C-C, C=C, a...
Two dimensional modeling of electromagnetic radiation and scattering by spectral element method Mahariq, İbrahim; Tarman, Işık Hakan; Kuzuoğlu, Mustafa; Department of Engineering Sciences (2014) In this thesis, the spectral element method is utilized in numerical modeling of two-dimensional, frequency-domain electromagnetic scattering and radiation problems. We perform domain truncation by the well-known perfectly matched layer (PML) and provide the corresponding formulation. The attenuation factor associated with the PML formulation is optimized so that the best accuracy is achieved for a wide range of Gauss- Legendre -Lobatto grids per wavelength. The optimality of the provided attenuation factor...
Magnetic ordering in two ferromagnetic sublattices of two mixed-valence iron(II)-iron(III) metal formate frameworks Yurtseven, Hasan Hamit (2019-11-01) Temperature dependence of magnetization (M) is calculated for two mixed-valence iron(II) - iron(III) metal formate frameworks (MOFs) with the two ferromagnetic sublattices below T-comp (compensation temperature) at 100 Oe by the molecular field theory. Temperature dependence of magnetization (M-T) is analyzed between T(comp )and T-ord = 39K (ordering temperature) by the power-law formula using the literature data for those compounds. Power-law analysis is also carried out for the field dependence of magneti...
