Description
Summary:Magnetic nanowires can be used to store information. There are various ways to write magnetic domains in nanowires, usually involving the use of an Oersted field. In this work the use of a spin torque oscillator to write domains in magnetic nanowires is investigated using micromagnetic modelling. It is shown that domains can be written using a lower magnetic field than if an Oersted field were used. Writing of multiple domains in a nanowire is also demonstrated.
