BINARY MIXTURES OF FERRO- AND ANTIFERROMAGNETIC BONDS IN QUANTUM SPIN-1 MODELS : CRITICAL BEHAVIOR

Abstract

A quantum spin-1 model, describing a mixture of ferro- and antiferromagnetic bonds, is analyzed employing the effective Hamiltonian method extended to random systems. Uniform, staggered and spin-glass susceptibilities are introduced and Curie, Néel and spin-glass transition temperatures determined. The role anisotropy is examined.

Monte Carlo Study of the Separation of Energy Scales in Quantum Spin 1/2 Chains with Bond Disorder

Beat Ammon, Manfred Sigrist

One-dimensional Heisenberg spin 1/2 chains with random ferro- and antiferromagnetic bonds are realized in systems such as $Sr_3 CuPt_{1-x} Ir_x O_6$. We have investigated numerically the thermodynamic properties of a generic random bond model and of a realistic model of $Sr_3 CuPt_{1-x} Ir_x O_6$ by the quantum Monte Carlo loop algorithm. For the first time we demonstrate the separation into three different temperature regimes for the original Hamiltonian based on an exact treatment, especially we show that the intermediate temperature regime is well-defined and observable in both the specific heat and the magnetic susceptibility. The crossover between the regimes is indicated by peaks in the specific heat. The uniform magnetic susceptibility shows Curie-like behavior in the high-, intermediate- and low-temperature regime, with different values of the Curie constant in each regime. We show that these regimes are overlapping in the realistic model and give numerical data for the analysis of experimental tests.

Monte Carlo Simulation for Random Mixtures of a Three-Dimensional Ising Site Model. II

T. Tatsumi

The critical properties of random mixtures of a three-dimensional Ising model have been studied with the Monte Carlo simulation for case III (JAA = JAB = -JBB = 1). It has been found that this system has ferro, antiferro and para phases but not the spin glass phase. The phase boundary between ferro and antiferro phases could not be determined explicitly. It also has been found that the critical behavior of this system changes with concentration.

Ground-State Phase Diagrams of the Two-Dimensional Quantum Heisenberg Spin Glass Models

Yoshihiko Nonomura, Yukiyasu Ozeki

Ground-state properties of the two-dimensional S = 1/2 random Heisenberg models are investigated by the exact-diagonalization method. The phase diagram of the bondrandom model (the ±J model) is the same as that of the corresponding Ising spin glass model, in spite of quantum fluctuation. In the site-random model, the spin glass phase exists at least in the ferro-rich case. In comparison with the corresponding Ising model, the Néel phase of this model becomes much narrower in the ferro-rich case, while it is comparable in the antiferro-rich case.

Ground-State Phase Diagrams of the Two-Dimensional Quantum Heisenberg Spin Glass Models

Yoshihiko Nonomura, Yukiyasu Ozeki

Ground-state properties of the two-dimensional $S=1/2$ random Heisenberg models are investigated by the exact-diagonalization method. The phase diagram of the bond-random model (the $\pm J$ model) is the same as that of the corresponding Ising spin glass model, in spite of quantum fluctuation. In the site-random model, the spin glass phase exists at least in the ferro-rich case. In comparison with the corresponding Ising model, the Néel phase of this model becomes much narrower in the ferro-rich case, while it is comparable in the antiferro-rich case.

Random Mixtures in Annealed and Quenched Ising Bond Model

Andrzej Pękalski, T. Oguchi

The two-dimensional Ising model with two kinds of bonds –ferro and antiferromagnetic– is investigated in both quenched and annealed approximations. High temperature series expansion technique is used to get the respective free energies and susceptibilities. Form the analysis of the ratio method results, the phase diagrams are drawn and critical concentrations are estimated. It is shown that in both approximations the system behaves similarly, although in the annealed case the magnetically ordered phases are more stable against increasing impurity concentration. It is also proved that for Bethe lattices initial susceptibilities for quenced and annealed systems coincide.

Ferromagnetic–spin-glass transition in a four-dimensional random-bond Ising model

Alexander K. Hartmann

The four-dimensional $\ifmmode\pm\else\textpm\fi{}J$ random-bond Ising model is studied using ground-state calculations. System sizes up to ${N=6}^{4}$ spins are considered. Here it is found that the ferromagnetic--spin-glass transition occurs at a critical concentration ${p}_{c}=0.28(1)$ of the antiferromagnetic bonds, which is comparable to values found previously by high-temperature series expansions. The transition is characterized by a correlation-length exponent $\ensuremath{\nu}=1.0(1)$ and an order-parameter exponent $\ensuremath{\beta}=0.4(1).$ Thus, this transition is in a different universality class from four-dimensional bond percolation, where $\ensuremath{\nu}=0.678(50)$ and $\ensuremath{\beta}=0.639(20).$
