概要

• 論文の詳細を見る

• An Ising system with axially long range antiferromagnetic interaction is discussed.A ferromagnetic nearest neighbor interaction exists in the plane perpendicular to theaxis. This system exhibits a devil's staircase phenomenon in the ground state; themagnetization changes in a rather strange way with external magnetic field. It isshown using a mean field approximation that, at finite temperatures, this system ex-hibits also a curious magnetization curve and some other interesting phenomena.However, the devil's staircase structure is destroyed by thermal fluctuation. A finitetemperature phase diagram, which is composed of many phases, is also given.
