چکیده
Motivated by recent experiments on (Sr,Ca,La) 14 Cu 24 O 41 , a two–dimensional Ising antiferromagnet with mobile, locally pinned and quenched defects is introduced and analysed using mainly Monte Carlo techniques. The interplay between the arrangement of the defects and the magnetic ordering as well as the effect of an external field are studied.

Ising and anisotropic Heisenberg magnets with mobile defects
Motivated by experiments on (Sr,Ca,La)14Cu24O41, a two–dimensional Ising model with mobile defects and a two– dimensional anisotropic Heisenberg antiferromagnet have been proposed and studied recently. We extend previous investigations by analysing phase diagrams of both models in external fields using mainly Monte Carlo techniques. In the Ising case, the phase transition is due to the thermal ...
متن کاملSpin Glasses on Thin Graphs
In a recent paper [1] we found strong evidence from simulations that the Ising antiferromagnet on “thin” random graphs Feynman diagrams displayed a mean-field spin glass transition. The intrinsic interest of considering such random graphs is that they give mean field theory results without long range interactions or the drawbacks, arising from boundary problems, of the Bethe lattice. In this pa...
متن کاملCriticality in the randomness-induced second-order phase transition of the triangular Ising antiferromagnet with nearest- and next-nearest-neighbor interactions
Using aWang-Landau entropic sampling scheme, we investigate the effects of quenched bond randomness on a particular case of a triangular Ising model with nearest(Jnn) and next-nearest-neighbor (Jnnn) antiferromagnetic interactions. We consider the case R = Jnnn/Jnn = 1, for which the pure model is known to have a columnar ground state where rows of nearest-neighbor spins up and down alternate a...

We study the dynamics of the critical two-dimensional fully-frustrated Ising model by means of Monte Carlo simulations. The dynamical exponent is estimated at equilibrium and is shown to be compatible with the value zc = 2. In a second step, the system is prepared in the paramagnetic phase and then quenched at its critical temperature Tc = 0. Numerical evidences for the existence of logarithmic...
متن کاملPinned magnetization in the antiferromagnet and ferromagnet of an exchange bias system
Using polarized neutron reflectometry, we obtained separate depth profiles for pinned and unpinned magnetization across the interface of a ferromagnet/antiferromagnet bilayer as a function of the sign of exchange bias. The pinned and unpinned magnetization depth profiles are nonuniform and extend well beyond the chemical interface, suggesting an interfacial region magnetically distinct from its...
