© 2022 IOP Publishing Ltd.The magnetic properties, martensitic transformation characteristics, the magnetic field-induced transformation characteristics, and super spin-glass behaviour at low temperature of Ni46.86Co2.91Mn38.17Sn12.06 (at%) magnetic shape memory alloys (MSMAs) were investigated under various magnetic field levels over temperature intervals from 400 K to 10 K. We observe a small magnetization difference during the martensitic transition evidenced with a visible thermal hysteresis. To investigate the magnetic field induced phase fraction, the minimum magnetic field required to start and complete the magnetostructural phase transition is computed. Super-spin glass features in magnetic data are observed that interacting magnetic clusters are frozen below a critical temperature. Magnetization is computed as a function of temperature at various constant fields using molecular field theory. The critical exponent, β is deduced for the temperature-induced magnetization, which indicates that the MSMA exhibited ferromagnetic ordering during field-cooling and on heating an antiferromagnetic ordering at low temperatures and in low applied magnetic fields. These observations are consistent within the framework of an Ising or Heisenberg model.

Analysis of the Critical Magnetic Field and the Dielectric Susceptibility for the Smectic A-Smectic C* Transition in DOBAMBC Yurtseven, Hasan Hamit (2015-01-01) The temperature dependences of the critical magnetic field H-c and the dielectric susceptibility x(at constant magnetic fields) are analyzed close to the smectic Asmectic C* transition in DOBAMBC using the experimental data according to a power-law formula. These analyses are performed below T-c in the smectic C* phase. Values of the critical exponent delta for the critical magnetic field are determined in a given temperature interval (Tc-T) with increasing and decreasing H-c. Also, values of the critical e...
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 ...
Investigation of the dynamic properties of ferroelectric crystals close to phase transitions Kiracı, Ali; Erkoç, Şakir; Department of Physics (2015) In this thesis we investigated the dynamical properties of some ferroelectric crystals and ceramics under various temperature and pressure conditions close to the phase transitions. In particular, we focused on the Raman frequencies, damping constant and the activation energy of soft modes with the pseudospin-phonon coupling in some ferroelectric crystals exhibiting phase transitions. We predicted the critical behavior of the frequency related to the order parameter (spontaneous polarization) in the ferroel...
A theoretical study of chemical doping and width effect on zigzag graphene nanoribbons Pekoz, Rengin; Erkoç, Şakir (Elsevier BV, 2009-12-01) The energetics and the electronic properties of nitrogen- and boron-doped graphene nanoribbons with zigzag edges have been investigated using density functional theory calculations. For the optimized geometry configurations, vibrational frequency analysis and wavefunction stability tests have been carried out. Different doping site optimizations for a model nanoribbon have been performed and formation energy values of these sites revealed that zigzag edgesite for both of the dopants were the most favorable ...
Investigation of effect of kaolin addition on combustion characteristic of olive residue Batır, Özge; Külah, Görkem; Selçuk, Nevin; Department of Chemical Engineering (2017) In this thesis study, effect of kaolin addition on combustion characteristic of olive residue was investigated by using thermogravimetric analyzer (TGA) combined with Fourier-transform infrared (FTIR) spectrometer in parallel with ash characteristics by X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD). The experiments were carried out by burning olive residue with 2%, 4% and 8% by wt. kaolin at 900˚C. Results reveal that addition of kaolin leads to decrease in rate of weight loss during char combustion ...
