We present here that nanomagnet networks provide a natural hardware platform for performing probabilistic computing in the Ising framework. By using a network of weakly coupled nanomagnets, we experimentally demonstrate for the first time the convergence of the network's magnetization towards the ground state of the associated Hamiltonian. The experimental results are in excellent agreement with the...
We introduce a modular, physics-based, spin-circuit SPICE model to analyze conventional (charge-voltage driven) and next-generation (spin-voltage driven) Magnetic Tunnel Junctions (MTJ) in a unified circuit framework. Proposed model has 3 important novelties: (1) Quantitatively matches representative experiments for charge-driven (c-MTJ) [1,2] and spin-driven MTJ (s-MTJ) devices [3], by solving transport...
Spin-Torque Nano-Oscillators (STNO) are of great research interest due to their compactness and scalability, GHz operation, frequency tunability, and integrability in existing CMOS process flow [1]. However, they have some short-comings that prevents commercial uptake. These are, broadly, the need of an external magnetic field for operation, low output power, poor Q-factor and high phase noise which...
