TL;DR: In this article, the authors demonstrate a 2.5-fold reduction in coercivity in FePt based exchange coupled composite bit patterned media (ECC-BPM) by coupling a lower anisotropy Co/Pd-Co/Ni-multilayer system to the top of a high anisotropic FePit L10 film.

TL;DR: In this paper, a micromagnetic study on the magnetization reversal in bit patterned media (BPM) with each bit consisting of an exchange coupled composite (ECC) layer stack is presented.

TL;DR: Following the evolution of the magnetic domain pattern in the system, it is suggested that domain walls are pinned on structural inhomogeneities given by the underlying nanoperforated template.

TL;DR: In this article, the authors present a systematic study on the magnetization reversal in square arrays of magnetic nanostructures and show that the variation in magnetic anisotropy within an array of magnetic nano-structures and the influence of magnetic dipole-dipole interaction between the individual bits with separation distance is crucial for the performance of bit patterned media (BPM) concerning in particular the switching field distribution.

TL;DR: In this article, the authors investigated the influence of bit size on the magnetization reversal mode and found that the transition from quasi-coherent to incoherent magnetization rotation process can still be described analytically if an activation volume is considered instead of the bit volume.
