Observation of the intrinsic pinning of a magnetic domain wall in a ferromagnetic nanowire
Magnetic domain walls can be controlled through a spin torque, which is usually influenced by extrinsic factors, such as defects, that pin the domain walls to specific configurations. It is now shown that intr...
