Amorphous magnetic alloys of cobalt-titanium

Abstract

Amorphous cobalt‐titanium films were deposited by r.f. sputtering for titanium content in excess of 14 atom percent. The properties of amorphous CoTi films are similar to those of transition metal‐metalloid glasses: they have soft magnetic properties and their resistivity is in the 100–200μΩcm range. Contrary to most metal‐metalloid glasses, these films have very small magnetostriction, are most thermally stable, and more corrosion resistant.
