Patent ID: 7842408

Claim:
A magnetic film comprising a multi-layered magnetic film which is formed by a body-centered cubic crystalline magnetic plated thin layer and a face-centered cubic crystalline magnetic plated thin layer; wherein the thickness of the body-centered cubic crystalline magnetic plated thin layer is larger than the thickness of the face-centered cubic crystalline magnetic plated thin layer; wherein the body-centered cubic crystalline magnetic plated thin layer and the face-centered cubic crystalline magnetic plated thin layer are 0.5 to 20 nm in thickness; wherein each layer of the multi-layered magnetic film has a different crystal structure from an immediately adjacent layer and epitaxial growth of each layer is broken by the immediately adjacent layer such that crystal grains of each layer are not larger than the thickness of their respective layer, and wherein the multi-layered magnetic film has at least four layers total of the body-centered cubic crystalline magnetic plated thin layer and the face-centered cubic crystalline magnetic plated thin layer alternately and sequentially stacked.
