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…
