Abstract
The behavior of an easy-plane spin antiferromagnetic chain with nodal spin S = 1 in external magnetic field is studied theoretically. It is shown that unlike the two-sublattice chain of spins S = 1/2, the syste m has no zero-magnetization phase at nonzero external field if there i s no one-ion magnetic anisotropy in the ground state. A high one-ion e asy-plane anisotropy gives rise to the phase.
