Abstract

PURPOSE: To improve corrosion resistance and durability, without deteriorating the electomagnetic converting characterisitcs of a magnetic metal thin film by implanting the ions of non-magnetic atoms into the surface of the thin film upon a non-magnetic substrate.
CONSTITUTION: A non-magnetic substrate 1, which is made of a high molecular substance having refractory property or non-magnetic metal, is formed thereon with a thin film 2 of magnetic metal such as a ferromagnetic metal simple substance composed mainly of Fe, Co and Ni. Non-magnetic ions such as Ar+, Cr+, Ta+, B+, Mo+, Al+, In+, Bi+ or Zn+ are implanted in number of 1015 to 1016/cm2 into the thin film 2 thereby to form an ion implanted layer 3.
