Novel Approach To Create High-density Magnetic Data Storage

In order to achieve higher storage densities on computer disks, the last decades were dominated by optimization of magnetic materials, i.e. the magnetic particles (grains) were gradually shrunk while, at the same time, the magnetic stability (magnetic anisotropy) was increased. Usually, about 100 to 600 grains form one bit, i.e. currently the smallest storage unit.[...]
