Skyrmion based energy efficient straintronic physical reservoir computing
Md Mahadi Rajib, Walid Al Misba, Md. Fahim F. Chowdhury +2
Physical Reservoir Computing (PRC) is an unconventional computing paradigm, which exploits nonlinear dynamics of reservoir blocks to perform recognition and classification tasks. H…
Focused Surface Acoustic Wave induced nano-oscillator based reservoir computing
Md. Fahim F. Chowdhury, Walid Al Misba, Md Mahadi Rajib +4
We demonstrate using micromagnetic simulations that a nanomagnet array excited by Surface Acoustic Waves (SAWs) can work as a reservoir that can classify sine and square waves with…
Energy Efficient Learning with Low Resolution Stochastic Domain Wall Synapse Based Deep Neural Networks
Walid A. Misba, Mark Lozano, Damien Querlioz +1
We demonstrate that extremely low resolution quantized (nominally 5-state) synapses with large stochastic variations in Domain Wall (DW) position can be both energy efficient and a…
Straintronics: Manipulating the Magnetization of Magnetostrictive Nanomagnets with Strain for Energy-Efficient Applications
Supriyo Bandyopadhyay, Jayasimha Atulasimha, Anjan Barman
The desire to perform information processing, computation, communication, signal generation and related tasks, while dissipating as little energy as possible, has inspired many ide…
Surface Acoustic Wave induced modulation of tunneling magnetoresistance in magnetic tunnel junctions
Dhritiman Bhattacharya, Peng Sheng, Md Ahsanul Abeed +6
We show that a surface acoustic wave (SAW) applied across the terminals of a magnetic tunnel junction (MTJ) decreases both the (time-averaged) parallel and antiparallel resistances…
Passive frustrated nanomagnet reservoir computing
Alexander J. Edwards, Dhritiman Bhattacharya, Peng Zhou +10
Reservoir computing (RC) has received recent interest because reservoir weights do not need to be trained, enabling extremely low-resource consumption implementations, which could…
Robust skyrmion mediated reversal of ferromagnetic nanodots of 20 nm lateral dimension with high Ms and moderate DMI
Md Mahadi Rajib, Walid Al Misba, Dhritiman Bhattacharya +1
Implementation of skyrmion based energy efficient and high-density data storage devices requires aggressive scaling of skyrmion size. Ferrimagnetic materials are considered to be a…
Modeling of Thermal Magnetic Fluctuations in Nanoparticle Enhanced Magnetic Resonance Detection
Tahmid Kaisar, Md Mahadi Rajib, Hatem ElBidweihy +2
We present a systematic numerical modeling investigation of magnetization dynamics and thermal magnetic moment fluctuations of single magnetic domain nanoparticles in a configurati…
Computing and Memory Technologies based on Magnetic Skyrmions
Hamed Vakili, Wei Zhou, Chung T Ma +13
Solitonic magnetic excitations such as domain walls and, specifically, skyrmionics enable the possibility of compact, high density, ultrafast,all-electronic, low-energy devices, wh…
