K. K. Meng, J. Lu, S. L. Wang, H. J. Meng, J. H. Zhao et al. We have investigated magnetic properties of laterally confined structures of epitaxial Fe films on GaAs (001). Fe films with different thicknesses were grown by molecular-beam epitaxy and patterned into regular arrays of rectangles with varying aspect ratios. In-plane magnetic anisotropy was observe ...
