Demonstration of Field-Coupled Input Scheme on Line of Nanomagnets

We report an electric and on-chip field-coupled input scheme for nanomagnet logic (NML). Deterministic control over the switching of a nanomagnet is demonstrated by applying synchronous clock and bias fields to first place the device in 0°/metastable state, and then tilt its magnetization in the appropriate direction. The clock field is generated on-chip by a CMOS-compatible clock line, while the bias field is generated by an input structure integrated with the clock line. Successful propagation of input data through ferromagnetic and antiferromagnetic coupling was observed along an L shaped NML line. This scheme can serve as an electric-magneto interface between CMOS and an NML circuit for NML inputs.
