Low ohmic loss radial superlattice conductors

摘要

Various examples are provided for low ohmic loss radial superlattice conductors. In one example, among others, a conductor includes a plurality of radially distributed layers that include a non-permalloy core, a permalloy layer disposed on and encircling the non-permalloy core, and a non-permalloy layer disposed on and encircling the permalloy layer. The non-permalloy core and non-permalloy layer can include the same or different materials such as, e.g., aluminum, copper, silver, and gold. In some implementations, the non-permalloy core includes a void containing air or a non-conductive material such as, e.g., a polymer. The permalloy layer can include materials such as, e.g., NiFe, FeCo, NiFeCo, or NiFeMo. In another example, a via connector includes the plurality of radially distributed layers including the permalloy layer and the non-permalloy layer disposed on and encircling the permalloy layer. The via connector can extend through glass, silicon, organic, or other types of substrates.
