摘要：
As first predicted by Haldane, and later observed in neutron-scattering experiments, one-dimensional Heisenberg antiferromagnets of integer spin have an excitation gap. Recently, the highly one-dimensional antiferromagnet Ni(C2H8N2)2NO2(ClO4) has been studied in an applied magnetic field. We discuss the susceptibility, high-field magnetization, and field-dependent neutron scattering using general arguments and field-theory methods. © 1990 The American Physical Society.
