Abstract: Amorphous magnetic metal alloys are processed by annealing at temperatures sufficient to achieve stress relief and cooling in directed magnetic fields or in zero magnetic fields. The ac and dc properties of magnetic cores produced in accordance with the processes of the invention may be tailored to match those of a wide range of magnetic alloys. Alloys processed in accordance with the invention provide improved performance in inductors, transformers, magnetometers, and electrodeless lamps.

Abstract: Plated memory wire is provided with a nickel-phosphorous alloy protective coating through an electro-deposition process. The protective coating is electrically conductive, nonmagnetic and has a bright surface amenable to good solder bonding. The memory function is provided by a Saccharin-type nickel-iron-cobalt film and the protective overcoating is applied by submerging the wire in an electrolyte bath composed of 360 g/l of nickel sulfate (NiSO.sub.4.6H.sub.2 O), 80 g/l of sodium sulfate (Na.sub.2 SO.sub.4), 60 g/l of sodium hypophosphite (NaH.sub.2 PO.sub.2.H.sub.2 O) and 25 g/l of boric acid (H.sub.3 BO.sub.3). The static bath is maintained at room temperature and the wire is moved through it at approximately eighteen inches per minute. An electro-deposition current density of from 20 to 80 ma./cm..sup.2 of plating area is employed.
