Phase transitions of the mixed spin-1/2 and spin-S Ising model on a three-dimensional decorated lattice with a layered structure
Jozef Strecka, Jan Dely, Lucia Canova
Phase transitions of the mixed spin-1/2 and spin-S (S >= 1/2) Ising model on a three-dimensional (3D) decorated lattice with a layered magnetic structure are investigated within th…
Ground-state phase diagram of geometrically frustrated Ising-Heisenberg model on doubly decorated planar lattices
Lucia Canova, Jozef Strecka, Jan Dely +1
Ground-state phase diagram of the mixed spin-1/2 and spin-1 Ising-Heisenberg model on doubly decorated planar lattices is examined using the generalized decoration-iteration transf…
Ternary-Spin Ising Model on an Anisotropically Decorated Square Lattice: An Exactly Solvable Case
Lucia Canova, Jozef Strecka, Jan Dely
Magnetic properties of a ternary-spin Ising model on the decorated square lattice are studied within a generalized decoration-iteration transformation. Depending on the mutual rati…
Phase diagram of the spin-1 XXZ Heisenberg ferromagnet with a single-ion anisotropy
Jozef Strecka, Jan Dely, Lucia Canova
Phase diagram of the spin-1 quantum Heisenberg model with both exchange as well as single-ion anisotropy is constructed within the framework of pair approximation formulated as a v…
Phase diagram of the spin-1 anisotropic Heisenberg model with a single-ion anisotropy
Jan Dely, Jozef Strecka, Lucia Canova
The spin-1 anisotropic Heisenberg model with a single-ion anisotropy is studied using the Oguchi's pair approximation. Although the theory is developed for lattices with general co…
Weak universal critical behaviour of the mixed spin-(1/2, S) Ising model on the union jack (centered square) lattice: integer versus half-odd-integer spin-S case
Jozef Strecka, Lucia Canova, Jan Dely
The mixed spin-(1/2, S) Ising model on the union jack (centered square) lattice is investigated by establishing the mapping relationship with its corresponding eight-vertex model.…
