Insights into nature of a magnetization plateau of 3$d$-4$f$ coordination polymer [Dy$_2$Cu$_2$]$_n$ from a spin-1/2 Ising-Heisenberg orthogonal-dimer chain

Autor: Strečka, J., Gálisová, L., Verkholyak, T.

Publikováno v: Condens. Matter Phys., 2020, vol. 23, No. 4, 43708

The ground state and magnetization process of an exactly solved spin-$1/2$ Ising-Heisenberg orthogonal-dimer chain with two different gyromagnetic factors of the Ising and Heisenberg spins are investigated in detail. It is shown that the investigated

Report

Magnetization plateaus and bipartite entanglement of an exactly solved spin-1/2 Ising-Heisenberg orthogonal-dimer chain

Autor: Gálisová, L., Strečka, J., Verkholyak, T., Havadej, S.

Publikováno v: Physica E 125 (2021) 114089

Spin-1/2 orthogonal-dimer chain composed of regularly alternating Ising and Heisenberg dimers is exactly solved in a presence of the magnetic field by the transfer-matrix method. It is shown that the ground-state phase diagram involves in total six d

Phase transitions of geometrically frustrated mixed spin-1/2 and spin-1 Ising-Heisenberg model on diamond-like decorated planar lattices

Autor: Galisova, L., Strecka, J.

Publikováno v: Condens. Matter Phys., 2011, vol. 14, No. 1, 13002:1-11

Phase transitions of the mixed spin-1/2 and spin-1 Ising-Heisenberg model on several decorated planar lattices consisting of interconnected diamonds are investigated within the framework of the generalized decoration-iteration transformation. The mai

Report

Ground-state properties of the spin-1/2 Heisenberg-Ising bond alternating chain with Dzyaloshinskii-Moriya interaction

Autor: Strecka, J., Galisova, L., Derzhko, O.

Publikováno v: Acta Phys. Pol. A 118 (2010) 742

Ground-state energy is exactly calculated for the spin-1/2 Heisenberg-Ising bond alternating chain with the Dzyaloshinskii-Moriya interaction. Under certain condition, which relates a strength of the Ising, Heisenberg and Dzyaloshinskii-Moriya intera
