A model based on an artificial neural network (ANN) was designed for the simulation and estimation of 2 theta and intensity values obtained by X-Ray Diffraction (XRD) of pure and La-doped barium ferrite powders which have been synthesized in ammonium nitrate melt. Its performance is evaluated by the influences of different La content, sintering temperature, Fe/Ba ratio, and washed in HCl (or not washed in HCl) samples. The XRD patterns of samples estimated by the ANN agree well with the experimental values, indicating that the model is reliable and adequate.

Modeling of Magnetic Properties of Nanocrystalline La-doped Barium Hexaferrite KÜÇÜK, İLKER; Sozeri, Huseyin; Ozkan, Husnu (Springer Science and Business Media LLC, 2011-05-01) In this paper an artificial neural network (ANN) has been developed to compute the magnetization of the pure and La-doped barium ferrite powders synthesized in ammonium nitrate melt. The input parameters were: the Fe/Ba ratio, La content, sintering temperature, HCl washing and applied magnetic field. A total of 8284 input data set from currently measured 35 different samples with different Fe/Ba ratios, La contents and washed or not washed in HCl were available. These data were used in the training set for ...
Molecular-dynamics simulations of surface and bulk properties of Zn, Cd, and ZnCd systems Amirouche, L; Erkoç, Şakir (Wiley, 2004-02-01) Surface and bulk properties of Zn, Cd, and ZnCd systems have been investigated by performing molecular-dynamics simulations using a recently developed empirical many-body potential energy function for these systems, which comprices two- and three-body atomic interactions. Surface reconstruction and multilayer relaxation on clean surfaces, adatom on surface, substitutional atom on surface and bulk materials, and vacancy on surface and bulk materials have been studied extensively.

Optical properties of (Ga2Se3)(0.)(75) - (Ga2S3)(0.)(25) single crystals by spectroscopic ellipsometry Işık, Mehmet; Hasanlı, Nızamı; Gasanova, L. (Elsevier BV, 2019-05-01) Structural and optical properties of 75 mol % Ga2Se3 - 25 mol % Ga2S3 system of single crystals were investigated by experimental techniques of x-ray diffraction (XRD), energy dispersive spectroscopy, Raman spectroscopy and ellipsometry. XRD pattern indicated that the studied compound has crystalline nature with cubic structure. Vibrational modes in the crystal were revealed using Raman spectroscopy experiments in the 90-450 cm(-1) frequency range and nine modes were observed in the spectrum. Ellipsometry m...
Phonon dispersions and elastic constants of disordered Pd-Ni alloys Kart, SO; Tomak, Mehmet; Cagin, T (Elsevier BV, 2005-01-31) Phonon frequencies of Pd-Ni alloys are calculated by molecular dynamics (MD) simulation. Lattice dynamical properties computed from Sutton-Chen (SC) and quantum Sutton-Chen (Q-SC) potentials as a function of temperature are compared with each other. We present all interatomic force constants up to the 8th nearest-neighbor shell obtained by using the calculated potential. Elastic constants evaluated by two methods are consistent with each other. The transferability of the potential is also tested. The result...
ANOMALOUS AMPLITUDE DEPENDENT DISLOCATION DAMPING ASSOCIATED WITH ANHARMONIC OSCILLATIONS OF A COULOMBIC KINK CHAIN IN THE NONLINEAR DISSIPATIVE ATMOSPHERE OF IMPURITY ATOMS OGURTANI, TO (Wiley, 1991-11-16) The effects of the anharmonic interaction of the Coulombic kink chain on the strength and the position of the cold-work internal friction peaks associated with the nonlinearly power dissipating impurity atoms are investigated by a novel numerical simulation of the related discrete mathematical macro-model. The present macroscopic model of dislocation damping which relies heavily on the microscopic theory of kink-interstitial interactions shows very strong anomalous strain amplitude as well as the bias stres...
