Abstract

We study the interaction between propagating domain walls in permalloy nanowires and nanomagnetic dots made of Co/Pt multilayers. The magnetic behavior of dots placed above/below the domain wall conductor is strongly influenced by the field of the wall. Using micromagnetic simulations we show that the field generated by the domain wall can switch the coupled dots to their magnetically ordered ground state. This effect can be exploited for clocking magnetic field-coupled devices and possibly substitute electrical clocking structures.
