Two dimensional XXZ-Ising model on square-hexagon lattice
J. S. Valverde, Onofre Rojas, S. M. de Souza
We study a two dimensional XXZ-Ising on square-hexagon (4-6) lattice with spin-1/2. The phase diagram of the ground state energy is discussed, shown two different ferrimagnetic sta…

Phase diagram of the asymmetric tetrahedral Ising-Heisenberg chain
J. S. Valverde, Onofre Rojas, S. M. de Souza.
The asymmetric tetrahedron is composed by all edges of tetrahedron represented by Ising interaction except one, which has a Heisenberg type interaction. This asymmetric tetrahedron…
