Electrical coupling of superparamagnetic tunnel junctions mediated by spin-transfer-torques
Leo Schnitzspan, Mathias Kläui, Gerhard Jakob
In this work, the effect of electrical coupling on stochastic switching of two in-plane superparamagnetic tunnel junctions (SMTJs) is studied, using experimental measurements as we…

Nanosecond True Random Number Generation with Superparamagnetic Tunnel Junctions -- Identification of Joule Heating and Spin-Transfer-Torque effects
Leo Schnitzspan, Mathias Kläui, Gerhard Jakob
This work investigates nanosecond superparamagnetic switching in 50 nm diameter in-plane magnetized magnetic tunnel junctions (MTJs). Due to the small in-plane uniaxial anisotropy,…
