We investigate the magnetic field distribution near the surface of a magneticsuperconductor when a magnetic source is placed close to the superconductor.The magnetic field distribution can be measured by magnetic force microscopyand scanning SQUID microscopy, from which one can extract both the penetrationdepth $\lambda_L$ and magnetic susceptibility $\chi$. When the magnetic momentsare parallel to the surface, one extracts $\lambda_L/\sqrt{1-4\pi \chi}$. Whenthe moments are perpendicular to the surface, one obtains $\lambda_L$. Bychanging the orientation of the crystal, one thus is able to extract both$\chi$ and $\lambda_L$.
