Indiffusion of Cobalt in Amorphous Co--Zr

By use of trilayers consisting of approx 35 nm cobalt, approx 45 nm amorphous Co--Zr, and approx 35 nm Co, the indiffusion of Co into the amorphous structure was studied by means of Rutherford backscattering spectroscopy (RBS). At temperatures between 650-690K, an initially high diffusion essentiall...

Description
Summary:By use of trilayers consisting of approx 35 nm cobalt, approx 45 nm amorphous Co--Zr, and approx 35 nm Co, the indiffusion of Co into the amorphous structure was studied by means of Rutherford backscattering spectroscopy (RBS). At temperatures between 650-690K, an initially high diffusion essentially stopped after 20-40 min annealing, before equilibrium was reached. It is proposed that the effect is related to the diffusional asymmetry in the amorphous phase. The relatively immobile Zr atoms cannot relax their configuration to permit Co indiffusion up to the equilibrium value. Graphs, Spectra. 16 ref.--AA
