Quantum Fluctuations in the Frustrated Antiferromagnet Sr2Cu3O4Cl2
Abstract Sr2Cu3O4Cl2 is an antiferromagnet consisting of weakly coupled CuO planes which comprise two weakly interacting antiferromagnetic subsystems, I and II, which order at respective temperatures TI ≈ 390K and TII ≈ 40K. Except asymptotically near the ordering temperature, these systems are good representations of the two-dimensional quantum spin 1/2 Heisenberg model. For T < TII there are ...
متن کاملFirst versus Second Order Phase Transition in Type 1 Antiferromagnet on the Fcc Lattice
-We have used Monte Carlo simulations to investigate Ising systems on the FCC lattice with antiferromagnetic first neighbour interactions (J1) and ferromagnetic second neighbour interactions (J2) ("type 1 antiferromagnet" ). Our results indicate that there is a first-order phase transition for J2/ I J1l up to at least as large as 1, a ratio four times as large as suggested by previous workers. ...
متن کاملOrder-disorder transition in a two-layer quantum antiferromagnet.
We have studied the antiferromagnetic order – disorder transition occurring at T = 0 in a 2-layer quantum Heisenberg antiferromagnet as the interplane coupling is increased. Quantum Monte Carlo results for the staggered structure factor in combination with finite-size scaling theory give the critical ratio Jc = 2.51 ± 0.02 between the inter-plane and in-plane coupling constants. The critical be...
متن کاملOrdering by Quantum Fluctuations in a Strongly Frustrated Heisenberg Antiferromagnet
The nature of the ordering of a quantum spin‐1/2 Heisenberg antiferromagnet is considered in the presence of the strong lattice frustration associated with the pyrochlore lattice. A field theory indicates that quantum fluctuations lead to a state having dimerization that has long‐range static correlations not in 〈S〉 but rather in 〈S(r)⋅S(r+δ)〉. A sublattice ordering is found that is consistent ...
متن کاملOrder by disorder and gaugelike degeneracy in a quantum pyrochlore antiferromagnet.
The (three-dimensional) pyrochlore lattice antiferromagnet with Heisenberg spins of large spin length S is a highly frustrated model with a macroscopic degeneracy of classical ground states. The zero-point energy of (harmonic-order) spin-wave fluctuations distinguishes a subset of these states. I derive an approximate but illuminating effective Hamiltonian, acting within the subspace of Ising s...
