Magnetic and magneto-transport properties of electrodeposited magnetic nano-network on laser modified Au surface

Magnetic nano-network structure has been fabricated by electrochemical deposition Ni onto laser modified Au film. Scanning electron microscopy images show that the network has a three-dimensional interconnecting branch structure with branch diameter of about 100 nm, constructed from grains with diameter of about 25 nm. Because of this structure, the Ni network has enhanced coercivity, in-plane isotropy, and a combination of longitudinal and transverse anisotropic magnetoresistance.
