摘要：

One-dimensional Heisenberg antiferromagnets of integer spin have disordered ground states with non-zero excitation gaps. A simple Landau-Ginsburg theory for Haldane gap antiferromagnets is presented. It is then used to discuss recent magnetisation and neutron scattering experiments on the quasi-one-dimensional antiferromagnet Ni(C2H8N2)2NO2ClO4 (NENP).
