摘要：
A theory of the doped spin-1/2 Heisenberg antiferromagnet (HA) is developed within the concept of a SO(3)-sigma model, recently studied [l] for the undoped system. Disordered states of the HA are discussed via topological defects of the SO(3)-sigma model supplemented by line defects due to discrete nature of lattice structure.
