Abstract

1,213,306. Magnetic structures. LIGNES TELEGRAPHIQUES ET TELEPHONIQUES. 14 Nov., 1967 [1 Dec., 1966], No. 51836/67: Heading H1H, [Also in Division C7] A thin film magnetic memory device comprises a thin film of Ni-Fe alloy and two sets of parallel conductors, each conductor operating on a large number of memory dots in the film. The film is produced by vacuum evaporation of Ni-Fe alloy, employing electron beam heating, and an unsaturated oxide of e.g. Si, Ti or Mn is incorporated in it by simultaneous evaporation or by prior deposition-on a substrate. After it is formed the Ni-Fe alloy film is annealed under a variable magnetic field.
