Abstract: The magnetic properties of 200 Å epitaxial Fe (001)/MgO (001) tiling are studied as a function of tile size and separation. For edge sizes above ~3 µm, the individual tiles maintain the single domain behavior while below ~3 µm the tiles break into domains due to demagnetizing effects. In addition, below an inter tile separation threshold of about 0.9 µm, a single tile magnetization switch provokes a reversal cascade in all the tiles; while, above this threshold, the individual tile's magnetization switches independently. In this last case, we have experimental access to the distribution of nucleation sites. Thus, we have found a clear signature of the magnetic interaction between patterned epitaxial micro tiles with in-plane magnetization.
