Magnetic images were obtained by scanning Hall probe microscopy. This involves rastering a GaAs Hall probe located in close proximity to a scanning tunnelling microscope tip over the sample of interest via a piezoelectric tube. At each step the Hall voltage is recorded and converted into a magnetic field via a known Hall co-efficient, thus producing the magnetic map.

Electronic transport measurements were performed by attaching gold wires with silver epoxy in a standard 5-lead Hall bar configuration. The in-plane resistivity was then measured as a function of temperature in a Quantum Design MPMS-7 system at Argonne National Labs.
