Abstract

en

Amorphization of the (Fe, Co, Ni, Al, Si)-Yb multilayered alloy films under Xe+ and Ar+ irradiation at room temperature is studied. It is found that (Co, Ni, Al, Si)-Yb alloy films are amorphized or partially amorphized by ion beam mixing, while Fe-Yb alloy films are not amorphized at two selected compositions. The recrystallization temperatures of the (Co, Ni, Al, Si)-Yb amorphous alloys are also determined.

Es wird die Amorphisierung von (Fe, Co, Ni, Al, Si)-Yb-Mehrfach-Legierungsschichten unter Xe+- und Ar+-Beschuß bei Zimmertemperatur untersucht. Es wird gefunden, daß (Co, Ni, Al, Si)-Yb-Legierungsschichten durch Ionenstrahlmischung amorphisiert oder teilweise amorphisiert werden, während Fe-Yb-Legierungsschichten bei zwei ausgewählten Zusammensetzungen nicht amorphisiert werden. Die Rekristallisierungstemperaturen der amorphen (Co, Ni, Al, Si)-Yb-Legierungen werden ebenfalls bestimmt.
