Influence of Annealing on the Magnetic and Transport Properties of Ag/Ni Multilayers

The properties of sputtered Ag/Ni multilayers have been investigated as a function of annealing treatment. The thermal evolution takes place in two stages. The first one, up to approx 450K, is attributed to interface sharpening. This leads to an improvement of the magnetic properties (almost linear...

Summary:The properties of sputtered Ag/Ni multilayers have been investigated as a function of annealing treatment. The thermal evolution takes place in two stages. The first one, up to approx 450K, is attributed to interface sharpening. This leads to an improvement of the magnetic properties (almost linear M(H) curves, higher T sub c and larger MR ratio). The second stage corresponds to the onset of destratification. This deteriorates the magnetic properties and leads to a decrease of the MR ratio.
