Abstract

Temperature dependent EPR studies were performed on a single crystal of CuSiO3.This recently discovered compound is isostructural with the spin-Peierls compound CuGeO3. The EPR signals show different characteristics than those of CuGeO3 and aredue to Cu2+ spins located along quasi one-dimensional chains. For T > 8.2K the spin susceptibility closely follows the predictions of a S=1/2 one-dimensional Heisenberg antiferromagnet with J/kB = 21K. Below T = 8.2K the spin susceptibility immediately drops to zero indicating long range magnetic order.
