Nonmagnetic impurities in two- and three-dimensional Heisenberg antiferromagnets.

In this paper we study in a large-S expansion effects of substituting spins by non-magnetic impurities in twoand threedimensional Heisenberg antiferromagnets in a weak magnetic field. In particular, we demonstrate a novel mechanism where magnetic moments are induced around non-magnetic impurities when magnetic field is present. As a result, Curie-type behaviour in magnetic susceptibility can be...

Imaging bond order near nonmagnetic impurities in square-lattice antiferromagnets.

We study the textures of generalized "charge densities" (scalar objects invariant under time reversal), in the vicinity of nonmagnetic impurities in square-lattice quantum antiferromagnets, by order parameter field theories. Our central finding is the structure of the vortex in the generalized density wave order parameter centered at the nonmagnetic impurity. Using exact numerical data from qua...

Nonmagnetic impurities in the spin-1 Õ2 kagome antiferromagnet

Motivated by recent experiments on ZnCu3 OH 6Cl2, we study the inhomogeneous Knight shifts local susceptibilities of a spin-1 /2 kagome antiferromagnet in the presence of nonmagnetic impurities. Using high temperature series expansion, we calculate the local susceptibility and its histogram down to about T=0.4J. At low temperatures, we explore a Dirac spin liquid proposal and calculate the loca...

Magnetic polarization induced by nonmagnetic impurities in high Tc cuprates

The magnetic polarization induced by nonmagnetic impurities such as Zn in high Tc cuprate compounds is studied by the variational Monte Carlo simulation. The variational wave function is constructed from the eigenstates obtained from Bogoliubov de Gennes mean field Hamiltonian for the twodimensional t − J model. A Jastrow factor is introduced to account for the induced magnetic moment and the r...

Effect of nonmagnetic impurities on stripes in high-Tc cuprates

We perform the numerically exact diagonalization study of the t-J model with nonmagnetic impurities to clarify the relation between Zn impurities and the stripes. By examining the hole-hole correlation function for a two-hole √ 18× √ 18 cluster with a single impurity, we find that the impurity has a tendency to stabilize vertical charge stripes. This tendency is caused by the gain of the kineti...
