摘要：

We investigate ground-state energies and magnetization curves in the one-dimensional XXZ model with next-to-nearest neighbor coupling alpha>0 and anisotropy Delta (-1 less than or equal to Delta less than or equal to 1) at T=0. In between the familiar ferro-and antiferromagnetic phase we find a transition region-called the metamagnetic phase-where the magnetization curve is discontinuous at a critical field B-c(alpha,Delta).
