Title: Soft magnetic thin film, and magnetic head and magnet recorder using soft magnetic thin film
Inventor: KIRINO FUMIYOSHI
IPC: G11B5/31
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To ensure good soft magnetic characteristics, and high thermal stability, high resistance to corrosion, and high reliability, by forming a compound with an element of at least one kind selected among Hf, Nb, Zr, Ta, and Al other than Fe and an element of at least one kind selected among C and N. SOLUTION: An Fe-Hf-N magnetic film in which a compound is formed by selecting, for example Hf among Hf, Nb, Zr, Ta and Al and N among C and N other than Fe is manufactured using a reactive sputtering method and using Fe85 Hf15 sintered structure as a target, and further using NH3 as an N fraction and Ar/NH3 (mixing ratio: 92/8) as discharge gas. The manufactured magnetic film is thermally treated at 600 deg.C for 30 minutes. Use of NH3 as the N fraction improves soft magnetic characteristics and further improves resistance to corrosion of a magnetic film. Further, a metal-in gap type head in which the soft magnetic thin film 1 is formed on a single crystal ferrite substrate 2 can be manufactured.

Abstract: PURPOSE:To obtain a high permeability by constituting a composite soft magnetic material to be used for motor, speaker and head with filament type soft magnetic material bound by the binding agent. CONSTITUTION:The soft iron, permalloy and 3% silicon steel are mixed and a mixture is rolled for obtaining filament. Thereby, the filament in diameter of 20-100mum can be obtained. It is then cut in such a length so that the ratio between length and diameter becomes 2-1,000.
