Determination of the steady-state kinetics in a spin-1 Ising model using path probability method
Özüm, Songül; Erdem, Rıza (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 ... -
Hysteretic behavior of quadrupolar ordering in a 2D magnetic spin˗1 Ising nanoparticle
Erdem, Rıza; Yalçın, Orhan; Özüm, Songül; Şahin, Ayşe; Demirer, Nazlı (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 ... -

Nanosized Monolayer on Square Lattice within Spin-1 Ising Model: Hysteretic Properties with Odd Interactions
Özüm, Songül; Kavlak, Ramazan; Erdem, Rıza; Yalçın, Orhan (Polish Acad Sciences Inst Physics, 2021)The hysteretic properties of a nanosized monolayer on the square lattice have been studied based on the spin-1 Ising model, including a single-ion anisotropy (D) and dipolar-quadrupolar (or odd, L) interaction parameters ... -
Relaxation times obtained from the rate equations using path probability method for the spin-1 Ising model
Erdem, Rıza; Özüm, Songül (World Scientific Publishing Co. Pte Ltd, 2019)We have presented the time-dependent behaviors of a spin-1 Ising model (with both bilinear and biquadratic interactions) in the neighborhood of the equilibrium states via the path probability method. The rate equations as ... -
Static and dynamic properties of two-sublattice spin-crossover systems
Yalçın, Orhan; Veliu, Valon; Özüm, Songül; Erdem, Rıza (Elsevier B.V., 2022)We investigate the static and dynamic properties of spin-crossover systems in the presence of an external magnetic field using two-sublattice Ising-like Hamiltonian. At low temperatures both sublattices are in the LS state, ...
