Recrystallization of multilayered CoNi/Cr films

1. When films with a cobalt and a chromium layer with respective thickness 50 and 500 nm are heated to 250–350°C, recrystallization occurs, resulting in the orientation Co (1011)/Cr (110) changing to Co (1120)/Cr (100). 2. In recrystallization the grain size remains almost unchanged. Grain growth is encountered solely during further heating. 3. A change of the orientation of the CoNi/Cr film in recrystallization leads to an increase of the coercive force and of the ratio Br/Bm.
