Ferrimagnetism and compensation points in a decorated 3D Ising models
We give a precise numerical solution for decorated Ising models on the simple cubic lattice which show ferromagnetism, compensation points, and reentrant behaviour. The models, consisting of S = 2 spins on a simple cubic lattice, and decorating S = 1 or S = 3 2 spins on the bonds, can be mapped exactly onto the normal spin2 Ising model, whose properties are well known. c © 2003 Elsevier B.V.

متن کاملFerrimagnetism 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 کاملTemperature and disorder chaos in three-dimensional Ising spin glasses.
We study the effects of small temperature as well as disorder perturbations on the equilibrium state of three-dimensional Ising spin glasses via an alternate scaling ansatz. By using Monte Carlo simulations, we show that temperature and disorder perturbations yield chaotic changes in the equilibrium state and that temperature chaos is considerably harder to observe than disorder chaos.
متن کاملSpin-Glass Phase in the Random Temperature Ising Ferromagnet
In this paper we study the phase diagram of the disordered Ising ferromagnet. Within the framework of the Gaussian variational approximation it is shown that in systems with a finite value of the disorder in dimensions D = 4 and D < 4 the paramagnetic and ferromagnetic phases are separated by a spin-glass phase. The transition from paramagnetic to spin-glass state is continuous (second-order), ...
متن کاملFerrimagnetism in GdCo(12-x)Fe(x)B6.
The effects of iron substitution on the structural and magnetic properties of the GdCo(12-x)Fe(x)B6 (0 ≤ x ≤ 3) series of compounds have been studied. All of the compounds form in the rhombohedral SrNi12B6-type structure and exhibit ferrimagnetic behaviour below room temperature: T(C) decreases from 158 K for x = 0 to 93 K for x = 3. (155)Gd Mössbauer spectroscopy indicates that the easy magnet...
