Abstract:

The magnetic properties of 2000-4000-angstrom-thick nickel-iron-cobalt films for potential use in computer memories, the preparation methods for these films, and their evaluation are discussed. A variety of nickeliron-cobalt alloy compositions were prepared to determine the particular alloy or group of alloys that would offer improvement over a straight nickel-iron alloy with re gard to magnetic characteristics such as lower coercivity, lower anisotropy, greater transverse loop linearity, and increased flux level. Optimum magnetic properties were achieved with a 74.1 nickel, 23.2 iron, 2.7 cobalt alloy film. This plated composition offers very desirable properties for application in computer memory arrays.
