Phase Diagram of the Two-Dimensional Ising Model with Random Competing Interactions

Octavio R. Salmon, J. Ricardo de Sousa, Fernando D. Nobre

An Ising model with ferromagnetic nearest-neighbor interactions $J_{1}$ ( $J_{1} > 0$ ) and random next-nearest-neighbor interactions [ $+ J_{2}$ with probability $p$ and $- J_{2}$ with p…

Magnetization Plateaux in the Antiferromagnetic Ising Chain with Single-Ion Anisotropy

Fabian Litaiff, J. Ricardo de Sousa, N. S. Branco

Two one-dimensional spin-1 antiferromagnetic Ising models with a single-ion anisotropy under external magnetic field at low temperatures are exactly investigated by the transfer-ma…
