| Abstract Scope |
In recent times, miniaturization and energy conservation of electronic devices have been demanded more intensively. There is the need for less environmental loads and accordingly for miniaturization of electronic components working at higher frequency. This leads to advanced inductors that are power dense and high temperature stable. The addressed alloys are typically cast into thin amorphous ribbons by planar flow casting processes. A short time annealing of the ribbons under tensile stress along the ribbon axis leads to huge anisotropy, respectively extremely small permeability. The temperature stability of magnetic properties is far superior to traditional Fe-based alloys. In particular, we will discuss the optimization of temperature stability as well as high frequency properties by applying new annealing and processing technologies based on an in-line tension anneal processing. Summarizing recent results of various strain annealed Co-rich or Fe-rich alloy compositions will be presented and opportunities for future application will be highlighted. |
