Magnetic and thermal properties of chiral metal formate frameworks (MOFs) of NH2NH3M(HCOO)(3), M = Fe, Mn, namely, HyFe and HyMn are investigated close to phase transitions by using Landau phenomenological model. By expanding the free energy in terms of the order parameter, for magnetic properties the temperature dependence of magnetization and inverse magnetic susceptibility, and for thermal properties the heat capacity and entropy are calculated for chiral HyFe and HyMn close to phase transitions using the experimental data from the literature. Additionally, structural order parameter and inverse susceptibility are predicted from the model, which can be compared with the observed data for chiral HyFe and HyMn.

Temperature-tuned band gap energy and oscillator parameters of Tl2InGaSe4 semiconducting layered single crystals
Hasanlı, Nızamı (Wiley, 2009-03-01)
The optical properties of Tl2InGaSe4 layered single crystals have been studied through the transmission and reflection measurements in the wavelength range of 500-1100 nm. The analysis of room temperature absorption data revealed the presence of both optical indirect and direct transitions with band gap energies of 1.86 and 2.05 eV, respectively. Transmission measurements carried out in the temperature range of 10-300 K revealed that the rate of change of the indirect band gap with temperature is gamma = -4...
Dispersive optical constants and temperature tuned band gap energy of Tl2InGaS4 layered crystals
Goksen, K.; Hasanlı, Nızamı; Ozkan, H. (IOP Publishing, 2007-06-27)
The optical properties of Tl2InGaS4 layered single crystals have been studied by means of transmission and reflection measurements in the wavelength range of 400-1100 nm. The analysis of the room temperature absorption data revealed the presence of both optical indirect and direct transitions with band gap energies of 2.35 and 2.54 eV, respectively. Transmission measurements carried out in the temperature range of 10-300 K revealed that the rate of change of the indirect band gap with temperature is gamma =...
Thermal lattice scattering mobility and carrier effective mass in intrinsic Tl2InGaTe4 single crystals
Qasrawi, A. F.; Hasanlı, Nızamı (IOP Publishing, 2007-04-18)
Systematic structural, dark electrical resistivity and Hall coefficient measurements have been carried out on n- type Tl2InGaTe4 single crystals. The data from x- ray powder diffraction allowed determination of the tetragonal unit cell lattice parameters. Analysis of the electrical resistivity and carrier concentration, which was recorded in the temperature range 210 - 350 K, reveals the intrinsic type of conduction with an average energy band gap of 0.85 eV. The temperature- dependent Hall mobility was obs...
Temperature and excitation intensity tuned photoluminescence in Tl4GaIn3S8 layered single crystals
Golksen, K.; Hasanlı, Nızamı (Wiley, 2008-05-01)
Photoluminescence spectra of Tl4GaIn3S8 layered crystals grown by Bridgman method have been studied in the wavelength region of 500-780 nm and in the temperature range of 26-130 K with extrinsic excitation source (lambda(exc) = 532 nm), and at T = 26 K with intrinsic excitation source (lambda(exc) = 406 nm). Three emission bands A, B and C centered at 514 nm (2.41 eV), 588 nm (2.11 eV) and 686 nm (1.81 eV), respectively, were observed for extrinsic excitation process. Variations in emission spectra have bee...
Composition dependency of lattice anisotropy of TlBX2-type chain mixed crystals
Hasanlı, Nızamı; Tas, M (Wiley, 2000-01-01)
Variation of the lattice parameters of TlTl1-xInxSe2 chain mixed crystals with composition have been studied by X-ray diffraction technique. The lattice anisotropy (c/a) of the TlBX2-type mixed crystals changes linearly with substitution of the atoms located bath at the center and at the vertices of the BX4 tetrahedra. A brief survey of the important features of the effect of isomorphic atom substitution on the lattice anisotropy of TlBX2-type mixed crystals with chain structure has been presented.
