Calculation of Magnetization and Magnetic Susceptibility Close to Magnetic Phase Transitions in (CH3)(2)(NH2FeNiII)-Ni-III(HCOO)(6) and (CH3)(2)(NH2FeCuII)-Cu-III(HCOO)(6)
Yurtseven, H.; Tarı, Özlem (Springer/Plenum Publishers, 2020)We study the temperature and magnetic field dependence of the magnetization (M) and the inverse susceptibility (chi(-1)) in the metal-organic frameworks, in particular, for (CH3)(2)(NH2FeNiII)-Ni-III(HCOO)(6) (DMFeNi) and ... -
Data-Driven Surrogate-Assisted Optimization of Metamaterial-Based Filtenna Using Deep Learning
Mahouti, Peyman; Belen, Aysu; Tarı, Özlem; Belen, Mehmet Ali; Karahan, Serdal; Koziel, Slawomir (MDPI, 2023)In this work, a computationally efficient method based on data-driven surrogate models is proposed for the design optimization procedure of a Frequency Selective Surface (FSS)-based filtering antenna (Filtenna). A Filtenna ... -
Magnetic Transitions in Two Novel Mixed-Valence Iron(Ii)–Iron(Iii) Metal Formate Frameworks : Two Sublattice Model
Yurtseven, Hasan Hamit; Tarı, Özlem (Elsevier B.V., 2022)We study the two-sublattice model in the mean field theory by expanding the Gibbs free energy in terms of the magnetizations M1 (Mup) and M2 (Mdown) with the quadratic coupling M12M22 (quadrupolar interactions) for the ... -
Thermodynamic study on the magnetic transition and structural phase transition in [(CH3)(2)NH2][Na0.5Fe0.5(HCOO)(3)] by using the Landau phenomenological model
Yurtseven, H.; Tarı, Özlem (Amer Inst. Physics, 2020)In this study, we apply the Landau phenomenological model to describe magnetic transition and structural phase transition in a metal formate framework (MOF) of the ferromagnetic [(CH3)(2)NH2][Na0:5Fe0:5(HCOO)(3)], namely, ...
