ABSTRACT:
A process for producing magnetic elements is disclosed in which magnetic material having a low copper content is utilized and, prior to deposition of copper for acting as a non-magnetic spacer, a layer of isolating material such as nickel is deposited to isolate the copper from the magnetic material so that, after mechanical working of the magnetic material to form an element and the element is annealed to restore its initial magnetic properties, the isolating layer acts to prevent the magnetic properties of the magnetic material from being degraded by the copper layer.
