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…
Energy based stochastic model for temperature dependent behavior of ferromagnetic materials
Sanjay Sah, Jayasimha Atulasimha
An energy based stochastic model for temperature dependent anhysteretic magnetization curves of ferromagnetic materials is proposed and bench marked against experimental data. This…
Modulating spin relaxation in nanowires with infrared light at room temperature
Md. Iftekhar Hossain, Saumil Bandyopadhyay, Jayasimha Atulasimha +1
Spintronic devices usually rely on long spin relaxation times and/or lengths for optimum performance. Therefore, the ability to modulate these quantities with an external agent off…
Reversible strain-induced magnetization switching in FeGa nanomagnets: Pathway to a rewritable, non-volatile, non-toggle, straintronic memory cell for extremely low energy operation
Hasnain Ahmad, Jayasimha Atulasimha, Supriyo Bandyopadhyay
Reversible straintronic switching of a nanomagnet's magnetization between two stable or metastable states promises ultra-energy-efficient non-volatile memory. Here, we report strai…
Electric field control of magnetic states in isolated and dipole-coupled FeGa nanomagnets delineated on a PMN-PT substrate
Hasnain Ahmad, Jayasimha Atulasimha, Supriyo Bandyopadhyay
We report observation of a "non-volatile" converse magneto-electric effect in elliptical FeGa nanomagnets delineated on a piezoelectric PMN-PT substrate. The nanomagnets are initia…
Self-similar Magneto-electric Nanocircuit Technology for Probabilistic Inference Engines
Santosh Khasanvis, Mingyu Li, Mostafizur Rahman +5
Probabilistic graphical models are powerful mathematical formalisms for machine learning and reasoning under uncertainty that are widely used for cognitive computing. However they…
Energy-efficient hybrid spintronic-straintronic reconfigurable bit comparator
Ayan K. Biswas, Jayasimha Atulasimha, Supriyo Bandyopadhyay
We propose a reconfigurable bit comparator implemented with a nanowire spin valve whose two contacts are magnetostrictive with bistable magnetization. Reference and input bits are…
Straintronic spin-neuron
Ayan K. Biswas, Jayasimha Atulasimha, Supriyo Bandyopadhyay
In artificial neural networks, neurons are usually implemented with highly dissipative CMOS-based operational amplifiers. A more energy-efficient implementation is a 'spin-neuron'…
