Magnetic impurities in half-integer-spin Heisenberg antiferromagnetic chains.
We study the efFect of an isolated impurity on the low-energy properties of a half-odd-integerspin Heisenberg antiferromagnetic chain using both numerical and conformal field theory techniques. The impurity corresponds to the substitution of a magnetic ion by a difFerent ion with the same or different spin, or else to the coupling of a magnetic impurity to a single spin on the chain. Depending ...
متن کاملDynamical Properties of Spin-Orbital Chains in a Magnetic Field
The excitation spectrum of the one-dimensional spin-orbital model in a magnetic field is studied, using a recently developed dynamical density matrix renormalization group technique. The method is employed on chains with up to 80 sites, and examined for test cases such as the spin-1/2 antiferromagnetic Heisenberg chain, where the excitation spectrum is known exactly from the Bethe Ansatz. In th...
متن کاملSpin reduction transition in spin - 32 random Heisenberg chains
Random spin3 2 antiferromagnetic Heisenberg chains are investigated using an asymptotically exact renormalization group. Randomness is found to induce a quantum phase transition between two random-singlet phases. In the strong randomness phase the effective spins at low energies are Se f f5 3 2 , while in the weak randomness phase the effective spins are Se f f5 1 2 . Separating them is a quant...
متن کاملBoundary Effects in Non-uniform Spin Chains
We give an explicit comparison of eigenvalues and eigenvectors of XY Hamiltonians of an open linear spin-1/2 chain and a closed spin-1/2 ring with periodic in space coefficients. It is shown that the Hamiltonian of a k-periodic chain with nk − 1 sites has (n − 1)k multiplicity one eigenvalues which are eigenvalues of multiplicity two for a Hamiltonian of a k-periodic ring with 2kn sites. For th...
متن کاملMagnetic properties of NaV2O5, a one-dimensional spin 1/2 Heisenberg system with finite chains
We have performed measurements of the magnetic susceptibility of NaV2O5 between 2 and 400 K. The high temperature part is typical of spin 1/2 chains with a nearest–neighbour antiferromagnetic exchange integral of 530 K. We develop a model for the susceptibility of a system with finite chains to account for the low temperature part of the data, which cannot be fitted by a standard Curie-Weiss te...
