摘要：

This paper numerically investigates the magnetoelastic instability in the S = 1/2 XXZ rings containing finite spins N with antiferromagnetic nearest-neighbour (NN) and next-nearest neighbour (NNN) coupling. It finds that, as the NN anisotropyΔ1 equals the NNN anisotropyΔ2, there exists a critical NNN coupling strength J2c (≈ 0.5), at which the systems always locate in dimerized phase for arbitrary large spring constant. AsΔ1 = Δ2, the values of J2c are dependent on N and the difference of (Δ1-Δ2).
