Energy-efficient switching of nanomagnets for computing: Straintronics and other methodologies
Noel D'Souza, Ayan Biswas, Hasnain Ahmad +7
The need for increasingly powerful computing hardware has spawned many ideas stipulating, primarily, the replacement of traditional transistors with alternate "switches" that dissi…
Polarized Neutron Reflectometry Study of Depth Dependent Magnetization Variation in Co Thin Film on a PMN-PT Substrate
Md Mamun Al-Rashid, Alexander Grutter, Brian Kirby +1
We studied the depth dependent magnetization profile of the magnetostrictive Co thin film layer in a PMN-PT (011)/Ta/Co/Ta structure under both zero and nonzero applied electric fi…
Image Processing with Dipole-Coupled Nanomagnets: Noise Suppression and Edge Enhancement Detection
Md Ahsanul Abeed, Ayan K. Biswas, Md Mamun Al-Rashid +2
Hardware based image processing offers speed and convenience not found in software-centric approaches. Here, we show theoretically that a two-dimensional periodic array of dipole-c…
Energy efficient and fast reversal of a fixed skyrmions with spin current assisted by voltage controlled magnetic anisotropy
Dhritiman Bhattacharya, Md. Mamun Al-Rashid, Jayasimha Atulasimha
Recent work [1,2] suggests that ferromagnetic reversal with spin transfer torque (STT) requires more current in a system in the presence of DMI than switching a typical ferromagnet…
Voltage controlled core reversal of fixed magnetic skyrmions without a magnetic field
Dhritiman Bhattacharya, Md Mamun Al-Rashid, Jayasimha Atulasimha
Using micromagnetic simulations we demonstrate core reversal of a fixed magnetic skyrmion by modulating the perpendicular magnetic anisotropy of a nanomagnet with an electric field…
Binary information propagation in circular magnetic nanodot arrays using strain induced magnetic anisotropy
M. Salehi-Fashami, M. Al-Rashid, Wei-Yang Sun +5
Nanomagnetic logic has emerged as a potential replacement for traditional CMOS-based logic because of superior energy-efficiency. One implementation of nanomagnetic logic employs s…
Dynamic Error in Strain Induced Magnetization Reversal of Nanomagnets due to Incoherent Switching and Formation of Metastable States: A Size-dependent Study
Md Mamun Al-Rashid, Supriyo Bandyopadhyay Jayasimha Atulasimha
Modulation of stress anisotropy of magnetostrictive nanomagnets with strain offers an extremely energy-efficient method of magnetization reversal. The reversal process, however, is…
Incoherent magnetization dynamics in strain mediated switching of magnetostrictive nanomagnets
Dhritiman Bhattacharya, Md Mamun Al-Rashid, Noel D'Souza +2
Micromagnetic studies of the magnetization change in magnetostrictive nanomagnets subjected to stress are performed for nanomagnets of different sizes. The interplay between demagn…
Geometry Effects in Switching of Nanomagnets with Strain: Reliability, Energy Dissipation and Clock Speed in Dipole-Coupled Nanomagnetic Logic
Md Mamun Al-Rashid, Jayasimha Atulasimha, Supriyo Bandyopadhyay
Strain-clocked dipole-coupled nanomagnetic logic is an energy-efficient Boolean logic paradigm whose progress has been stymied by its propensity for high error rates. In an effort…
