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.
