We present in this talk a recent analysis for the magnetic moments of thebaryon antidecuplet within the framework of the chiral quark-soliton model withlinear $m_s$ corrections considered. We take into account the mixing of higherrepresentations to the collective magnetic moment operator, which comes fromthe SU(3) symmetry breaking. Dynamical parameters of the model are fixed byexperimental data for the magnetic moments of the baryon octet as well as bythe masses of the octet, decuplet and of $\Theta^{+}$. The magnetic moment of$\Theta^{+}$ is rather sensitive to the pion-nucleon sigma term and ranges from$-1.19 {\rm n.m.}$ to $-0.33 {\rm n.m.}$ as the sigma term is varied from$\Sigma_{\pi N} = 45$ to 75 MeV, respectively. On top of them, we obtained thatthe strange magnetic moment of the nucleon has the value of $\mu^{(s)}_N=+0.39$ n.m. within this scheme and turns out to be almost independent of thesigma term.Comment: 7 pages, 1 figure, A talk given at International Workshop on  PENTAQUARK04, SPring-8, Hyogo, Japan, 20-23 Jul 200
