Tohoku University Technology: Giant Magnetoresistance Magnetic Tunnel Junction Device: T21-109
Improved stability of operation against external magnetic fields.
In recent years, magnetic tunnel junctions (MTJs) have attracted attention as solid-state devices capable of generating random output signals, with applications expected in random number generation units for probabilistic computing systems. However, superparamagnetic MTJs, designed to have a magnetic direction in the free layer that is easily disturbed by thermal fluctuations, are sensitive to external magnetic fields due to their small anisotropic magnetic field, making them susceptible to external magnetic influences even from fields of a few mT. The present invention is a technology that offers excellent operational stability (robustness) against external magnetic fields, suitable for superparamagnetic MTJs, and supports the social implementation of computing systems using them.
