We systematically investigate the temperature dependence of the anomalous Hall effect within SRO membranes of varying thicknesses. In addition, extensive characterization is performed via X-ray diffraction. The exfoliation process is shown to release the epitaxial strain while maintaining long-range crystallinity, thus producing highly ordered, strain-free, conducting ferromagnetic membranes. These electronic and magnetic properties were found to be comparable to their epitaxial counterparts, paving the way towards prospective atomically-thin itinerant ferromagnetic membranes.
