Spin-orbit (SO) coupling can be introduced in a Bose--Einstein condensate(BEC) as a gauge potential acting only in a localized spatial domain. Effect ofsuch a SO "defect" can be understood by transforming the system to theintegrable vector model. The properties of the SO-BEC change drastically if theSO defect is accompanied by the Zeeman splitting. In such a non-integrablesystem, the SO defect qualitatively changes the character of solitoninteractions and allows for formation of stable nearly scalar soliton complexeswith almost all atoms concentrated in only one dark state. These solitons existonly if the number of particles exceeds a threshold value. We also report onthe possibility of transmission and reflection of a soliton upon its scatteringon the SO defect. Scattering strongly affects the pseudo-spin polarization andcan induce pseudo-spin precession. The scattering can also result in almostcomplete atomic transfer between the dark states.
