On the loci of relaxation time and magnetic dispersion maxima in the Mean-Field Ising model
(Sakarya University Journal of Science SAUJS, 2020)
Based on the phenomenological approach, loci of relaxation time and magnetic dispersion maxima near the critical regime in a spin-1/2 mean-field Ising model were performed. The shift in temperature (T) of relaxation time ...
Hysteretic properties of magnetization and quadrupolar moment in the blume-emery-griffiths model under the pair approximation
(L.N. Gumilyov Eurasian National University, 2020)
The magnetic hysteresis (M-H) and quadrupole hysteresis (Q-D) loops have been investigated for the Blume-Emery-Griffiths (BEG) model using the pair approximation. The observed curves strongly depend on biquadratic exchange ...
Nanosized Monolayer on the Square Lattice within Spin-1 Ising Model: Magnetic Properties with odd Interactions
(2020)
Based on the spin-1 Ising model Hamiltonian with dipolar (bilinear, J), quadrupolar, (biquadratic, K), dipolar-quadrupolar (odd, L) interactions and single-ion anisotropy parameter (D), magnetic properties of the nanosized ...
Synthesis and investigation of small g-values for smart spinel ferrite nanoparticles
(Elsevier Science Sa, 2021)
Smart spinel and hexagonal ferrite nanoparticles (NPs) have been fabricated by ethylenediaminetetraacetic acid (EDTA) and cetyltrimethylammonium bromide (CTAB) assisted hydrothermal route by using NaOH solution. Electron ...
Hysteretic behavior of quadrupolar ordering in a 2D magnetic spin˗1 Ising nanoparticle
(Physical Society of the Republic of China, 2021)
Pair approximation technique has been used to study the quadrupolar ordering properties for the 2D magnetic spin-1 Ising nanoparticles, consisting of core and surface parts with an interface coupling. Similar to the magnetic ...

As a continuation of previously published work [A. Erdinç and M. Keskin, Int. J. Mod. Phys. B 18, 1603 (2004), doi:10.1142/S0217979204024823] the hysteretic properties of magnetization (m) and quadrupolar moment (q) have ...
Determination of the steady-state kinetics in a spin-1 Ising model using path probability method
(World Scientific Publ Co PTE Ltd, 2020)
As a continuation of our previously published work, we propose a theoretical framework for the determination of steady-state kinetics in a spin-1 Ising model by the path probability method. The framework is based on the ...
Ising-like model for the two-step spin-crossover systems: Static properties with magnetic field effects using cluster variation method
(Institute of Molecular Physics, Polish Academy of Sciences Faculty of Physics, Adam Mickiewicz University, Poznań, 2021)
We investigate the static properties of a two−sublattice Ising−like Hamiltonian for spin-crossover (SCO) systems in the presence of an external magnetic field. Self−consistent equations are obtained using cluster variation ...
Widom lines related with the relaxational dynamics for the Ising model
(MECO, 2021)
We have presented a phenomenological description for the relaxation dynamics (RD) of Ising ferromagnets in the presence of external magnetic field (h). We calculate two characteristic times using the rate constants which ...
