Spin orbit torque controlled stochastic oscillators with synchronization and frequency tunability
Punyashloka Debashis, Aman K. Maskay, Pramey Upadhyaya +1
Stochastic oscillators based on emerging nanodevices are attractive because of their ultra-low power requirement and ability to exhibit stochastic resonance, a phenomenon where syn…
Electric field control of interaction between magnons and quantum spin defects
Abhishek Bharatbhai Solanki, Simeon I. Bogdanov, Avinash Rustagi +10
Hybrid systems coupling quantum spin defects (QSD) and magnons can enable unique spintronic device functionalities and probes for magnetism. Here, we add electric field control of…
Hardware implementation of Bayesian network building blocks with stochastic spintronic devices
Punyashloka Debashis, Vaibhav Ostwal, Rafatul Faria +3
Bayesian networks are powerful statistical models to understand causal relationships in real-world probabilistic problems such as diagnosis, forecasting, computer vision, etc. For…
Electrically-Tunable Stochasticity for Spin-based Neuromorphic Circuits: Self-Adjusting to Variation
Hossein Pourmeidani, Punyashloka Debashis, Zhihong Chen +2
Energy-efficient methods are addressed for leveraging low energy barrier nanomagnetic devices within neuromorphic architectures. Using a Magnetoresistive Random Access Memory (MRAM…
