N2 - We investigated surface morphologies of Ni thin films evaporated on polyethylene naphtalate (PEN) organic substrates for the fabrication of spin quantum cross structures and discussed its feasibility toward ferromagnetic nanojunctions from a viewpoint of the Ni grain size and the Ni surface roughness. The grain size for Ni films of sub-10-nm thickness is ∼30 nm, which is larger than the Ni thickness, and the surface roughness, in the scanning scale of the film thickness, is less than 0.25 nm, corresponding to one-atomic-layer thickness. These experimental results indicate that spin quantum cross structures which consist of Ni thin films on PEN substrates can be expected as a candidate of ferromagnetic nanojunctions, which may lead to large magnetoresistance effect.
