Abstract

We describe a technique for generating local magnetic fields at megahertz rates along magnetic nanowires. Local and global magnetic fields are generated from buried copper fine-pitch wires fabricated on 200 mm silicon wafers using standard complementary metal-oxide-semiconductor back-end process technology. In combination with pump-probe scanning Kerr microscopy, we measure the static and dynamic propagation fields of domain walls in permalloy nanowires.
