We present a local probe study of the magnetic superconductor,ErNi$_2$B$_2$C, using magnetic force microscopy at sub-Kelvin temperatures.ErNi$_2$B$_2$C is an ideal system to explore the effects of concomitantsuperconductivity and ferromagnetism. At 500 mK, far below the transition to aweakly ferromagnetic state, we directly observe a structured magneticbackground on the micrometer scale. We determine spatially resolved absolutevalues of the magnetic penetration depth $\lambda$ and study its temperaturedependence as the system undergoes magnetic phase transitions from paramagneticto antiferromagnetic, and to weak ferromagnetic, all within the superconductingregime. In addition, we estimate the absolute pinning force of Abrikosovvortices, which shows a position- and temperature dependence as well, anddiscuss the possibility of the purported spontaneous vortex formation.
