We investigate the variant regularly diluted situations of [Formula: see text] in S=1 isotropic antiferromagnetic chains by the quantum Monte Carlo loop cluster algorithm. Our results manifest significant different magnetic properties in the ground state with respect to the odd (even) host S=1 spins in one unit cell with an impurity S=1/2, and the doped system gradually transits to the pure Haldane chain in two different tendencies with the decreasing of the impurity concentrations.

Quantum Monte Carlo Simulations

The S =1/2 Heisenberg chain with bond alternation and randomness of antiferromagnetic (AFM) and ferromagnetic (FM) interactions is investigated by quantum Monte Carlo simulations of loop/cluster algorithm. Our results have shown interesting finite temperature magnetic properties of this model. The relevance of our study to former investigation results is discussed.
