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 ...
Nanosized Monolayer on Square Lattice within Spin-1 Ising Model: Hysteretic Properties with Odd Interactions
(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 ...
Phenomenological Dynamics of Ising Magnets in the Presence of Magnetic Field: Widom Lines Captured from Slow Relaxation Time
(2021)
A complete phenomenological description for the relaxation dynamics of the Ising ferromagnets in the presence of external magnetic field h is given by using the pair approximation. To study the relaxation dynamics, we ...
Origin of Cross-Over Phenomenon of Hysteresis Loops and High Absorption Loss Properties for Spinel Ferrite Nanoparticles
(Polish Acad Sciences Inst Physics, 2021)
Spinel ferrite nanoparticles have been synthesized by the surfactant-assisted hydrothermal route using cetyltrimethylammonium bromide (CTAB) and ethylenediaminetetraacetic acid (EDTA) in the NaOH solution. Temperature ...
Dipolar and Quadrupolar Hysteresis in Core-Surface Magnetic Nanoparticles
(2019)
Blume-Emery-Griffiths (BEG) model [1] is used to investigate the hysteretic behaviour of dipole (M) and quadrupole ordering (Q) properties peculiar to core/surface (C/S) type hexagonal Ising nanoparticles (HINPs) [2-3]. ...
Static and dynamic properties of two-sublattice spin-crossover systems
(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, ...
Static properties of spin-crossover with magnetic interaction of Spin-1 Blume-Emery-Griffiths model for two-sublattices
(2022)
The static properties of the spin-1 Blume-Emery-Griffiths (BEG) model for two-sublattices with the presence of an external magnetic field for spin-crossover (SCO) and magnetic ordering are presented. To study the static ...
