  • Patent number: 11075026
    Abstract: Embodiments herein describe techniques for a magnetic conductive device including a substrate, an under layer above the substrate, and a magnetic conductive layer including NiFe alloy formed on the under layer. A method for forming a magnetic conductive device includes forming a support stack including an under layer above a substrate, cleaning the support stack, and performing electrodeposition on the under layer by placing the support stack into a plating bath to form NiFe alloy on the under layer. The NiFe alloy includes Ni in a range of about 74% to about 84%, and Fe in a range of about 26% to about 16%. Other embodiments may be described and/or claimed.
    Type: Grant

  • Patent number: 4977038
    Abstract: Micro- and nano-porous metal structures including an alloy of one or more noble metals and substantially uniform and interconnected porosity in pore sizes ranging from three nanometers to 10 micrometers produced by a process including the following steps: mixing at least two metals having different electrochemical activity, according to predetermined proportions to form a multi-metallic alloy; contacting said alloy with an electrolyte; and applying an electrochemical potential to said electrolyte wherein said alloy acts as the anode until all or a portion of the more electrochemically active metal is dissolved from the alloy leaving porous metal.
