Probabilistic spin logic that relies on tunable random number generators (tRNGs) has attracted great interest in unconventional computing paradigm. In this work, we propose an effective tRNG based on spin-orbit torque induced stochastic switching of a nanomagnet with perpendicular magnetic anisotropy. The switching probability is dependent on both the applied in-plane magnetic fields and the currents, and is fitted well with the sigmoidal function. The result provides an alternative building block for unconventional computing systems.
