Abstract

The magnetization process of the S = 1 spin ladder with two anisotropies competing each other is investigated using the numerical diagonaization of finite-size clusters and the level spectroscopy analysis. As a result, it is found that the translational symmetry broken magnetization plateaux appear at 1/4 and 3/4 of the saturation magnetization. The phase diagrams with respect to the anisotropies at the 1/4, 1/2 and 3/4 magnetizations are obtained. The magnetization curves for several typical parameters are also presented.

Translational Symmetry Broken Magnetization Plateau of the S = 1 2 Anisotropic Spin Ladder with Ferromagnetic Rung Interaction

Tôru Sakai, Koki Doi, Kiyomi Okamoto +5 more

Abstract The magnetization process of the S = 1/2 anisotropic spin ladder with the ferromagnetic rung interaction is investigated using the numerical diagonalization of finite-size clusters. It is found that the translational symmetry broken magnetization plateau would appear at half the saturation magnetization, when the competing anisotropies are sufficiently large. The phase diagram with respect to the anisotropies and several magnetization curves are presented.

Translational-Symmetry-Broken Magnetization Plateaux of the S = 3/2 Anisotropic Antiferromagnetic Chain

The magnetization process of the $S=3/2$ quantum spin chain with the $XXZ$ anisotropy and the single-ion anisotropy $D$ is investigated using the numerical diagonalization of finite-size clusters and the level spectroscopy analysis. We obtain the phase diagrams at 1/3 and 2/3 of the saturation magnetization to find that the translational-symmetry-broken magnetization plateau appears for the first time. The similarity and the difference between the phase diagrams of the present model and the related models are discussed by use of the discrete parameters of the models. In addition several typical magnetization curves are presented.

Translational symmetry broken magnetization plateau of the S=1 antiferromagnetic Heisenberg chain with competing anisotropies

Tôru Sakai, Kiyomi Okamoto, Kouichi Okunishi +4 more

We investigate the $S=1$ antiferromagnetic quantum spin chain with the exchange and single-ion anisotropies in a magnetic field, using numerical exact diagonalization of finite-size clusters, level spectroscopy analysis, and the density matrix renormalization group (DMRG). We find that a translational symmetry broken magnetization plateau possibly appears at the half of the saturation magnetization, when the anisotropies compete with each other. The level spectroscopy analysis gives the phase diagram at half the saturation magnetization. The DMRG calculation presents the magnetization curves for some typical parameters and clarifies the spin structure in the plateau phase.

Translational Symmetry Broken Magnetization Plateau of the \(S = 2\) Antiferromagnetic Chain with Anisotropies

The magnetization plateau of the S = 2 antiferromagnetic chain with interaction and singleion anisotropies is investigated using the numerical diagonalization of finite-size clusters and some size scaling analyses.The previous level spectroscopy analysis indicated that two different magnetization plateau phases appear at half of the saturation magnetization.One is due to the large-D mechanism and the other is due to the Haldane one.In the present study the phase diagram is extended to wider region of the anisotropies.As a result we find another half magnetization plateau phase, where the translational symmetry is spontaneously broken .

Magnetization Process of anS=1 Frustrated Spin Ladder

Kiyomi Okamoto, Kouichi Okunishi, Tôru Sakai

We investigate, at T =0, the magnetization process of the S =1 frustrated two-leg spin ladder having the leg interaction ( J ), the rung interaction ( J 0 ) and the diagonal interaction ( J d ), especially focusing on the appearance and the disappearance of the magnetization plateaux. We use the degenerate perturbation theory, the level spectroscopy analysis of the numerical diagonalization data and the DMRG. When J d =0, the M s /2 plateau ( M s is the saturation magnetization) appears for J 0 / J > 1.463. Then there is no M s /2 plateau for the so-called isotropic case J = J 0 . In case of J d > 0, J d helps the M s /2 plateau. And also, the M s /4 and (3/4) M s plateaux appear when J d is sufficiently large. These two plateaux are associated with the spontaneous breaking of the translation symmetry along the leg direction. We show the plateau phase diagram on the J d versus J plane, and also the magnetic phase diagram on the H versus J d plane for fixed J .
