  We investigate the effects of strong magnetic fields on the properties of
hyperon stars. The matter is described by a hadronic model with parametric
coupling. The matter is considered to be at zero temperature, charge neutral,
beta-equilibrated, containing the baryonic octet, electrons and muons. The
charged particles have their orbital motions Landau-quantized in the presence
of strong magnetic fields (SMF). Two parametrisations of a chemical potential
dependent static magnetic field are considered, reaching $1-2 \times
10^{18}\,G$ in the center of the star. Finally, the Tolman-Oppenheimer-Volkov
(TOV) equations are solved to obtain the mass-radius relation and population of
the stars.
