Spin-Reorientation Transition of Field-Induced Magnetic Ordering Phases in the Anisotropic Haldane System

Hiroshi Miyazaki, Tomohiko Hiwasa, Masataka Oko +1 more

A possible spin-reorientation transition in field-induced magnetic ordering phases of the S=1 Haldane system with large easy-plane anisotropy is proposed, using an effective Lagrangian formalism as well as the density matrix renormalization group method. Such a spin-reorientation transition is predicted in the case where the applied magnetic field is inclined from the easy axis of the anisotropy. We point out that this transition has a close connection with a variation of the order parameter even at zero temperature, although it is different from a quantum analog of the so-called spin-flop transition proposed for the system having a strong easy axis anisotropy. In connection with a novel phase observed recently in the Haldane system at high fields, we discuss possible implications for the field-induced magnetic ordering.

Crossover Behavior of Magnetic Excitations in the Anisotropic Haldane Antiferromagnet under High Magnetic Fields

Hiroshi Miyazaki, Isao Harada

Field-induced magnetic phases are investigated in the one-dimensional S = 1 Haldane system with the easy-plane anisotropy under external magnetic fields along an arbitrary direction, using the density-matrix renormalization group method. At a critical field the system exhibits the quantum phase transition from the nonmagnetic Haldane phase to a magnetic phase. It is found that the quantum analog of the classical soliton bearing system is induced except for the case where the field is applied perpendicular to the easy plane. In the exceptional case, Tomonaga-Luttiger spin-fluid state is realized. The angle dependence of the critical field is discussed in connection with two consecutive field-induced phase transitions observed in NDMAP. Possible implications for such novel transitions are given.
