Dynamics of 1D Magnetic Topological Structures

ORAL

Abstract

In one dimensional ferromagnetic wires domains of collinear ferromagnetic order can be separated by different types of topological, and non-topological, domain walls. Domains of opposite orientation are typically separated by either Bloch or Néel domain walls, whereas domains of the same orientation can be separated by magnetic impurities, or by a one dimensional equivalent of a skyrmion which may be found in quasi-one dimensional wires. We consider the different current induced dynamics and stability of these various magnetic deformations. We will go on to make a thorough investigation of the different magnetoresistance which can be caused by these various forms of domain walls, paying particular attention to the one dimensional skyrmion.
