Electrolytic Photoetching of Vitrovac 6025 for the Production of Magnetic Recording Heads
Spring 1985
Work carried out in 1959 at the California Institute
of Technology yielded a novel gold-silicon alloy
with an amorphous structure’. This discovery
initiated extensive research into the production of
new metal-metalloid amorphous metal alloys of
approximate composition T80M20; T80 represents
80 atomic per cent of one or more transition metals
such as iron, nickel and cobalt, and M20 represents
20 atomic per cent of one or more of the metalloid
(glass-former) elements such as boron, carbon,
silicon and phosphorus.
