  We have systematically investigated the magnetic moments and magnetic form
factors of the decuplet baryons to the next-to-next-leading order in the
framework of the heavy baryon chiral perturbation theory. Our calculation
includes the contributions from both the intermediate decuplet and octet baryon
states in the loops. We also calculate the charge and magnetic dipole form
factors of the decuplet baryons. Our results may be useful to the chiral
extrapolation of the lattice simulations of the decuplet electromagnetic
properties.
