Ising ferrimagnetic system on a layered honeycomb lattice
نویسنده
چکیده
The magnetic properties of a mixed spin-2 and spin5 2 Ising ferrimagnetic system on a layered honeycomb lattice are studied. In particular we investigate the effect of a single-ion anisotropy and an interlayer interaction on the compensation phenomenon, in order to clarify the characteristic features observed in a series of molecular-based magnets AFeFe (C2O4)3@A5N(n-CnH2n11)4 , n53 –5]. We carried out Monte Carlo simulations and found that an interlayer interaction plays one of the roles for the existence of a compensation point. It is pointed out that a compensation point may be possible even if interlayer interactions are zero, provided there are other longer-range interactions.

Ferrimagnetism in Diluted Mixed Spin-1/2 and Spin-3/2 Ising Systems
Using an effective field theory with correlations we study a diluted mixed spin-112 and spin-312 Ising ferrimagnetic system with a crystal field interaction D(D < 0) on a honeycomb lattice. We find that the system may exhibit two compensation points in the total magnetization curve, although the corresponding system in the absence of dilution or with D = 0 never exhibits any compensation point ...
متن کاملTheory of the Random Magnetic Mixture . I - - Ising System -
A theory of the random magnetic mixture of some kinds of Ising spins is formulated in terms of distribution functions which are introduced for the thermal averages of each kind of spins. The distribution functions are determined from a simultaneous non-linE)ar integral equation of order n, where n is the number of kinds of spins. By the use of this theory, the magnetic properties of a honeycomb...

In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4), ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...
متن کاملFrustrated mixed spin-1/2 and spin-1 Ising ferrimagnets on a triangular lattice.
Mixed spin-1/2 and spin-1 Ising ferrimagnets on a triangular lattice with sublattices A, B, and C are studied for two spin-value distributions (S(A),S(B),S(C))=(1/2,1/2,1) and (1/2,1,1) by Monte Carlo simulations. The nonbipartite character of the lattice induces geometrical frustration in both systems, which leads to the critical behavior rather different from their ferromagnetic counterparts....
متن کاملComplex - temperature singularities in the d = 2 Ising model : triangular and honeycomb lattices
We study complex-temperature singularities of the Ising model on the triangular and honeycomb lattices. We first discuss the complex-T phases and their boundaries. From exact results, we determine the complex-T singularities in the specific heat and magnetization. For the triangular lattice we discuss the implications of the divergence of the magnetization at the point u = − 3 (where u = z2 = e...
