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]. ... -
Dünya ve Türkiye’de bazı nanoteknoloji çalışmaları
(Niğde Ömer Halisdemir University, 2019)Atom, maddenin tüm özelliklerine sahip, hücre ise canlının tüm özelliklerini gösteren en küçük yapılardır. Büyüklük olarak karşılaştıracak olursak, hücre yaklaşık olarak atomdan 100.000 defa daha büyüktür. “Nano” sözcük ... -
Dynamic susceptibility for a spin-1 Isingmodel using the path probability method
(Niğde Ömer Halisdemir University, 2019)The nonlinear rate equations based on the path probability method is used to derive the dynamic (or complex) susceptibility ( ) for a spin-1 Ising model with bilinear and biquadratic interactions when the external magnetic ... -
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 ... -
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 ... -
Nanosized monolayer on the square lattice within spin-1 ising Model: Hysteretic properties with odd interactions
(L.N. Gumilyov Eurasian National University, 2020)We propose a theoretical framework for the investigation of M-H and Q-D hysteresis loops for the nanosized monolayer on the square lattice within spin-1 Ising model Hamiltonian with dipolar (J), quadrupolar (K), ... -
Spin-1 Ising modelinde manyetik dağılganlık bağıntısı ve manyetik sönüm faktörünün yol olasılık metodu ile hesaplanması
(2019)Bu çalışmada, önceki çalışmamızın [1] devamı olarak, manyetik alan altında bilineer (J) ve bikuadratik (K) etkileşme Hamiltonyenli spin-1 Ising Modeli [2, 3] için dinamik (yani kompleks) alınganlık ifadesi X= X¹ iX²[4, ... -
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 ... -
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 ...
