Effect of Single-Ion Anisotropy on Stability of Quantum and Thermal Entanglement in a Mixed-Spin Heisenberg Trimer
Hana Vargová, Jozef Strečka
The effect of uniaxial single-ion anisotropy on quantum entanglement is rigorously quantified using negativity in a mixed spin-(,,) Heisenberg trimer, accounting for dif…
Rotating magnetoelectric effect in a ground state of a coupled spin-electron model on a doubly decorated square lattice
Hana Čenčariková, Jozef Strečka
Exact analytical calculations are performed to study the rotating magnetoelectric effect in a ground state of a coupled spin-electron model on a doubly decorated square lattice wit…
Genuine tripartite entanglement in a mixed spin-(1/2,1) Heisenberg tetramer
Hana Vargová, Jozef Strečka
A genuine tripartite entanglement of a mixed spin-(1/2,1) Heisenberg tetramer is rigorously analyzed in a presence of external magnetic field. The couple of mixed spin-(1/2,1) dime…
Magnetoelastic properties of a spin-1/2 Ising-Heisenberg diamond chain in vicinity of a triple coexistence point
N. Ferreira, J. Torrico, S. M. de Souza +2
We study magnetoelastic properties of a spin-1/2 Ising-Heisenberg diamond chain, whose elementary unit cell consists of two decorating Heisenberg spins and one nodal Ising spin. It…
Unconventional strengthening of a bipartite entanglement of a mixed spin-(1/2,1) Heisenberg dimer achieved through Zeeman splitting
Hana Čenčariková, Jozef Strečka
The bipartite quantum and thermal entanglement is quantified within pure and mixed states of a mixed spin-(1/2,1) Heisenberg dimer with the help of negativity. It is shown that the…
Magnetic behavior of a ferro-ferrimagnetic ternary alloy ABC with a selective site disorder: the case study of a mixed-spin Ising model on a honeycomb lattice
Jordana Torrico, Jozef Strečka, Onofre Rojas +2
Phase transitions, compensation phenomenon and magnetization of a ferro-ferrimagnetic ternary alloy ABC composed of three different kinds of magnetic ions A, B and C wi…
Enhanced magnetoelectric effect of exactly solved spin-electron model on a doubly decorated square lattice in vicinity of a continuous phase transition
Hana Čenčariková, Jozef Strečka
Magnetoelectric properties of a coupled spin-electron model on a doubly decorated square lattice in an external electric field applied along the crystallographic axis [11] are rigo…
