摘要：

A magnetic tunnel junction (MTJ) is a bistable magnetic device and typically used as magnetic random access memory. When the potential barrier separating the two bistable states is reduced, such a device can also be used as a true random-number generator (TRNG). Here we show that a millitesla magnetic field transverse to the magnetization equilibrium direction can effectively control the potential barrier in an MTJ-based TRNG, and realize a random-number generation rate up to gigahertz, several orders of mag-nitude higher than the existing MTJ-based devices. Furthermore, such field-modulating MTJ-TRNG can also function as a probabilistic bit with tunable activation time for the purpose of probabilistic computing.
