creator Camras, Marvin A method of making a magnetic transducer head or element thereof from a binary alloy of silicon and iron, preferably containing from about 3 percent to 7 percent of silicon by weight, including provision of a grain-oriented silicon-iron core, annealing the core at a temperature above the Curie point in a dry hydrogen atmosphere and during cooling from that temperature subjecting the core piece to a magnetic field applied in the direction of the working flux at the core. The annealed core piece is formed so as to provide a gap-defining face for coupling to a magnetic record medium, the gap being of the order of about 1 micron.
