Title: BaCu[sub 2]Si[sub 2]O[sub 7]: A quasi-one-dimensional S=1/2 antiferromagnetic chain system

Abstract

The antiferromagnetic (AF) compound BaCu[sub 2]Si[sub 2]O[sub 7] is studied by magnetic susceptibility and neutron-scattering techniques. The observed behavior is dominated by the presence of loosely coupled S=1/2 chains with the intrachain AF exchange constant J[sub [parallel]][approx]24.1 meV. Long-range N[acute e]el ordering is observed below T[sub N] =9.2 K. The results are discussed within the framework of the mean-field RPA model for weakly interacting quantum spin chains.
