Amorphization of AuBi Alloys by Laser Quenching and Ion Irradiation


Crystalline Au100−x Bix alloy films (20<≤ x ≤ 90) could be transformed into an amorphous state by either laser (20 ns pulse length, 248 nm) or ion bombardment (Ar ions, 300 keV) of these films, which were mounted onto a substrate kept at low temperatures (<10K). Several metastable phases could be obtained by annealing of the amorphous phase before the starting equilibrium phase mixture was formed. The different phases were characterized by their different superconducting and electrical properties.
