Multilayer plasmon generator
A plasmon generator has a front end face located in a medium facing surface of a magnetic head. The plasmon generator includes a metal portion and a multilayer film portion. The metal portion has a bottom surface, a top surface, and an end face facing toward the front end face. The multilayer film portion includes a first metal layer, a second metal layer and an intermediate layer, and covers the top surface and the end face of the metal portion. The intermediate layer is formed of a material that is higher in Vickers hardness than the metal material used to form the metal portion, the metal material used to form the first metal layer and the metal material used to form the second metal layer.
