We reanalyse the magnetic moments of the baryon octet, decuplet, andantidecuplet within the framework of the chiral quark-soliton model, with SU(3)symmetry breaking taken into account. We consider the contributions of themixing of higher representations to the magnetic moment operator arising fromthe SU(3) symmetry breaking. Dynamical parameters of the model are fixed byexperimental data for the magnetic moments of the baryon octet and from themasses of the octet, decuplet and of $\Theta^{+}$. The magnetic moment of$\Theta^{+}$ depends rather strongly on the pion-nucleon sigma term and reads$-1.19 {\rm n.m.}$ to $-0.33 {\rm n.m.}$ for $\Sigma_{\pi N} = 45$ and 75 MeVrespectively. The recently reported mass of $\Xi^{--}_{\bar{10}}(1862)$ iscompatible with $\Sigma_{\pi N} = 73$ MeV. As a byproduct the strange magneticmoment of the nucleon is obtained with a value of $\mu^{(s)}_N =+0.39$ n.m.Comment: RevTeX is used. 12 pages, 3 figures, final version for publication in  Phys.
