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, ... -
