Abstract
A non-magnetic conductor material, a magnetic transducer element having formed therein a non-magnetic conductor layer formed of the non-magnetic conductor material and a method for forming a magnetic transducer element having formed therein the non-magnetic conductor layer formed of the non-magnetic conductor material. The non-magnetic conductor material comprises an alloy comprising nickel and at least one non-magnetic conductor metal selected from the group consisting of copper at a weight percent of from about 45 to about 90, zinc at a weight percent of from about 20 to about 75, cadmium at a weight percent of from about 35 to about 85, platinum at a weight percent of from about 55 to about 90 and palladium at a weight percent of from about 75 to about 95. The non-magnetic conductor material contemplates the magnetic transducer element and the method for forming the magnetic transducer element. The non-magnetic conductor material has physical properties, chemical properties and electrochemical properties, but not magnetic properties, analogous to the physical properties, chemical properties and electrochemical properties exhibited by magnetic layers employed within magnetic tran…
