“…Magnetic studies of amorphous REx-Fe(100-x) thin films indicate that, for the heavier rare-earth metals, these films show a ferromagnetic behaviour [24,27]. Recently, RE-TM nanostructures based on antidots have shown a strong potential for energy-assisted recording on nanometre-scale magnetic media, magneto-optic perpendicular recording patterned media based on template-assisted deposition techniques and ultrafast spintronic technology [8,[28][29][30] In this work, we pay special attention to the basic magnetic properties such as the magnetic anisotropy, Curie temperature, effective magnetic anisotropy energy, remanence and coercivity angular dependence, of Dy-Fe alloy antidot arrays by studying the effect of the geometrical parameters as they are, shape and size of nanohole, holes spatial ordering and antidot film thickness, on their magnetic properties. In addition, the influence of hexagonal ordering symmetry of nanoholes arrangement on the magnetothermal behaviour as compared to the continuous thin film samples has been investigated.…”
