Abstract:

Zero-point spin reduction in the low-dimensional antiferromagnet is discussed by the spin wave theory taking into account kinematical interaction due to finite magnitude of spin. This method is applied to KCuF₃ and the result is in good agreement with the observed one. Furthermore the values of zero-point spin reduction of several other chain-structure antiferromagnets are predicted.
