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 the multilayer perceptron (MLP) neural network trained by Levenberg-Marquardt learning algorithm. The hyperbolic tangent and sigmoid transfer functions were used in the hidden layer and output layer, respectively. The correlation coefficients for the magnetization were found to be 0.9999 after the network was trained.

Phase Identification of La-Doped Hard Magnetic Barium Ferrite Using Artificial Neural Network Sozeri, Huseyin; KÜÇÜK, İLKER; Ozkan, Husnu (Springer Science and Business Media LLC, 2011-01-01) 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,...
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.

Stability analysis of graphene nanoribbons by molecular dynamics simulations Dugan, N.; Erkoç, Şakir (Wiley, 2008-04-01) In this work, stability of graphene nanoribbons are investigated using molecular dynamics. Simulations include heating armchair and zigzag-edged nanoribbons of widths varying between one and nine hexagonal rings until the bonds between carbon atoms start to break. Breaking temperatures and binding energies per atom for different widths are presented for both armchair and zigzag-edged cases. A nontrivial relation between stability and width is observed and discussed.
Evolution of magnetic and structural properties of TiO2 with Co-doping Topal, Ugur; Ozkan, Husnu; Bakan, Halil I.; Cankur, Oktay; Topal, Kevser (Elsevier BV, 2008-03-15) This paper presents the phase formations and magnetic properties of Co-doped TiO2 synthesized by the colloidal and ammonium nitrate melt techniques (ANMT). The phase formations and ferromagnetic properties were studied with XRD and SQUID magnetometry. Crystallization of the TiO2 rutile lattice was completed at 1000 degrees C and that was preserved during annealing up to 1300 degrees C. For the samples annealed at 1200 degrees C, elemental analysis has shown that the colloidal technique leads to a single-pha...
Investigation of structural, electronic, magnetic and lattice dynamical properties for XCoBi (X: Ti, Zr, Hf) Half-Heusler compounds Surucu, Gokhan; IŞIK, MEHMET; CANDAN, ABDULLAH; Wang, Xiaotian; Güllü, Hasan Hüseyin (Elsevier BV, 2020-06-15) Structural, electronic, magnetic, mechanical and lattice dynamical properties of XCoBi (X: Ti, Zr, Hf) Half-Heusler compounds have been investigated according to density functional theory and generalized gradient approximation. Among alpha, beta and gamma structural phases, gamma-phase structure has been found as the most stability characteristics depending on the calculated formation enthalpies, energy-volume dependencies and Cauchy pressures. Energy-volume plots of possible magnetic orders of gamma-phase ...
