Magnetocaloric and electrocaloric properties of the Hubbard pair cluster
K. Szałowski, T. Balcerzak
The paper contains the discussion of the magnetocaloric and electrocaloric effect in a model dimer (pair cluster). The system of interest is modelled with a Hubbard Hamiltonian inc…
The Pair Approximation method for the ferromagnetic Heisenberg model with spin and arbitrary range of interactions. Application for the magnetic semiconductor CrIAs
T. Balcerzak, K. Szałowski
The Pair Approximation method has been formulated for the isotropic ferromagnetic Heisenberg model with spin . The exchange interactions of arbitrary range have been taken int…
Thermodynamic properties of the one-dimensional Ising model with magnetoelastic interaction
T. Balcerzak, K. Szałowski, M. Jaščur
The Ising one-dimensional (1D) chain with spin and magnetoelastic interactions is studied with the lattice contribution included in the form of elastic interaction and ther…
Hubbard pair cluster with elastic interactions. Studies of thermal expansion, magnetostriction and electrostriction
T. Balcerzak, K. Szałowski
The pair cluster (dimer) is studied within the framework of the extended Hubbard model and the grand canonical ensemble. The elastic interatomic interactions and thermal vibrationa…
Spin-glass-like ordering in a frustrated Ising antiferromagnet on a honeycomb lattice
M. Žukovič, M. Borovský, A. Bobák +2
We study the nature of a low-temperature phase in the frustrated honeycomb-lattice Ising model with first- and second-neighbor antiferromagnetic (AF) interactions, and ,…
Hubbard pair cluster in the external fields. Studies of the polarization and susceptibility
T. Balcerzak, K. Szałowski
The electric and magnetic polarizations as well as the electric and magnetic susceptibilities of the Hubbard pair-cluster embedded in the external fields were studied by the exact…
