Abstract :
The magnetic properties of FeTb rf-sputtered thin films have been investigated. While the as-prepared films are mainly amorphous, a successive annealing process caused the development of successive crystal phases. We observed the emergence of a variety of different domain structures, as the system crystal fraction evolves. The hysteretic behavior is shown to change as the internal stresses are released by annealing.
