Abstract
We present calculations of the decuplet baryon magnetic moments in the chiral quark model. As input we use parameters obtained in qualitativ ely accurate fits to the octet baryon magnetic moments studied previou sly. The values found for the magnetic moments of Delta(++) and Omega( -) are in good agreement with experiments. We finally calculate the to tal quark spin polarizations of the decuplet baryons and find that the y are considerably smaller than what is expected from the non-relativi stic quark model.
