Abstract

We report an electric, field-coupled input scheme for nanomagnet logic (NML). Furthermore, input structures are integrated with CMOS compatible clock structures for NML. This paper describes the controlled switching of the magnetization state of a nanomagnet by applying a locally generated biasing field to a device that has been placed in a 0°/metastable state by a clad, current carrying clock line. Fringing fields from the set device can then change the state of another, adjacent nanomagnet. This scheme can serve as an electric-magnetic interface between CMOS and an NML circuit.
