Experimental Clocking of Nanomagnets with Strain for Ultralow Power Boolean Logic Noel D’Souza Mohammad Salehi Fashami Supriyo Bandyopadhyay Jayasimha Atulasimha 10.1021/acs.nanolett.5b04205.s001 https://acs.figshare.com/articles/journal_contribution/Experimental_Clocking_of_Nanomagnets_with_Strain_for_Ultralow_Power_Boolean_Logic/2071822 Nanomagnetic implementations of Boolean logic have attracted attention because of their nonvolatility and the potential for unprecedented overall energy-efficiency. Unfortunately, the large dissipative losses that occur when nanomagnets are switched with a magnetic field or spin-transfer-torque severely compromise the energy-efficiency. Recently, there have been experimental reports of utilizing the Spin Hall effect for switching magnets, and theoretical proposals for strain induced switching of single-domain magnetostrictive nanomagnets, that might reduce the dissipative losses significantly. Here, we experimentally demonstrate, for the first time that strain-induced switching of single-domain magnetostrictive nanomagnets of lateral dimensions ∼200 nm fabricated on a piezoelectric substrate can implement a nanomagnetic Boolean NOT gate and steer bit information unidirectionally in dipole-coupled nanomagnet chains. On the basis of the experimental results with bulk PMN–PT substrates, we estimate that the energy dissipation for logic operations in a reasonably scaled system using thin films will be a mere ∼1 aJ/bit. 2016-02-04 16:35:17 magnetostrictive nanomagnets Ultralow Power Boolean LogicNanomagnetic implementations logic nanomagnetic Boolean NOT gate PMN substrate Spin Hall effect bit information unidirectionally dissipative losses
