Abstract
We systematically investigate the mass spectrum, spatial configuration and magnetic moment of the ground and p-wave states

with various color-spin configurations in a multiquark color flux-tube model. Numerical results indicate that the state Zcs
(4000)+ can be described as the compact state

with 13S1. Its main color-spin configuration is

and its magnetic moment is 0.73μ

with 11

with other quantum numbers in the model.
