Magnetic structures

Computer simulations showing the complex motion of a domain wall as it is driven through a Ni80Fe20 nanowire by an applied magnetic field. The black arrows indicate the direction of the magnetisation in the two magnetic domains the domain wall separates, while the colour contrast indicates the local direction of the magnetisation at each point in the nanowire.
