Abstract
Magnetic properties for the one-dimensional multicomponent quantum spin
system with the excitation gap are studied based on the integrable spin model
introduced by Bariev et al. By exactly computing the magnetization, we
show how the characteristic structure with plateaus and cusps appears in the
magnetization process. To study low-energy dynamics of the system, we apply the
finite-size scaling analysis to the excitation spectrum, and thereby evaluate
the power-law exponent as well as the enhancement factor for the
low-temperature NMR relaxation rate 1/T_1. We discuss the critical properties
of 1/T_1 around plateaus and cusps in the magnetization curve.
