Abstract
- This work delineates the thermally stable, self-biased straintronic nanomagnetic logic (NML) by leveraging the dipole coupling between an array of nanomagnets using only two electrodes that discard the intricate voltage mechanism of multi-electrode systems. For efficient NML operation, the self-biased elliptical nanomagnets with fixed aspect ratio can be designed over a particular thickness range, limited by the thermal stability and shape anisotropy energy. Micromagnetic simulations show that the 180° magnetization switching of the nanomagnet is assisted by an external applied voltage and the dipole coupling, allowing controlled NML operations. The relationship between the critical switching frequency and critical strain is used to select the appropriate nanomagnets for different logic operations. [ABSTRACT FROM AUTHOR]
