This report describes the surface profile, magnetic properties and thermal stability of amorphous Fe<SUB>78</SUB>Si<SUB>10</SUB>B<SUB>12</SUB> ribbons fabricated by melt-spinning using a copper roll in vacuum, He, Ar, N<SUB>2</SUB> and air. Ribbons fabricated in Ar, N<SUB>2</SUB> or air have surface profiles with long deep scratches due to gas bubbles injected along the melt-roll interface, while the scratches on the surface profiles of ribbons fabricated in He or vacuum are greatly reduced in a number and size. The different characteristics of the surface profiles are associated with improvements in the magnetic and thermal properties of the ribbons fabricated in He or vacuum.
