ABSTRACT:
A base member is disposed in a reaction chamber and a raw material gas is introduced thereinto which contains at least a compound gas of a first magnetic material, or the compound gas of the first magnetic material and an oxidizing or nitriding gas, or the compound gas of the first magnetic material and a compound gas of a second magnetic material. A plasma generating electrical energy is applied to the raw material gas to obtain therein a stream of plasma of the raw material gas, by which a stream of active reaction products is passed over the base member. As a result of this, the first magnetic material, an oxide or nitride of the first magnetic material, or a magnetic material containing the first and second magnetic materials is deposited on the base member, forming thereon a magnetic material layer which consists principally of the first magnetic material, the oxide or nitride of the first magnetic material, or the magnetic material containing the first and second materials.
