The discrete nature of crystal lattices plays a role in virtually every material property. But it is only when the size of entities hosted by a crystal becomes comparable to the lattice period—as occurs for dislocations, vortices in superconductors and domain walls—that this discreteness is manifest explicitly. The associated phenomena are usually described in terms of a background Peierls ‘atomic washboard’ energy potential, which was first introduced for the case of dislocation motion in the… 

Ferroelectric domain wall dynamics characterized with X-ray photon correlation spectroscopy

This work introduces X-ray photon correlation spectroscopy (XPCS) as a powerful tool for investigating heterogeneous dynamics of interfaces and shows how to distinguish the dynamics related to the passing of domain walls through the periodic (Peierls) potential of the crystal lattice and through the random potential caused by lattice defects (pinning centers).

Motion of domain walls and the dynamics of kinks in the magnetic Peierls potential.

It is predicted that, despite the discreteness of the system, kinks can behave like sine-Gordon solitons in thin films of materials such as yttrium iron garnets, and general conditions for other materials are derived.

Atomic antiferromagnetic domain wall propagation beyond the relativistic limit

We theoretically investigate the dynamics of atomic domain walls (DWs) in antiferromagnets driven by a spin-orbit field. For a DW with a width of a few lattice constants, we identify a Peierls-like

The recent advent of atomically-thin ferromagnetic crystals has allowed experimental studies of two-dimensional (2D) magnetism that not only exhibits novel behavior due to the reduced dimensionality

Kryder’s law predicts a doubling of the capacity of commodity hard drive devices every 13 months. However, the capacity did not increase as expected in the past three years. Perhaps today’s hard

In ferromagnetic materials with large anisotropy constants (K1 > 108 erg/cm3) the domain wall width, δB, is of the order of magnitude of a few lattice constants (10 to 30 A). The spin configuration
