Towards Ultra Scalability of Non-Volatile Magnetic Tunnel Junctions with a 3D Storage Layer
Nuno Caçoilo, Shunsuke Fukami, Olivier Fruchart +1
The perpendicular Spin Transfer Torque Magnetic Random Access Memory is one of the most promising emerging non-volatile memory technologies, based on ultra-thin magnetic tunnel jun…
Single-shot laser-pulse-induced magnetization reversal in CoFeB/MgO-based magnetic tunnel junctions
Junta Igarashi, Sébastien Geiskopf, Takanobu Shinoda +9
We demonstrate single-shot laser-pulse-induced magnetization reversal in rare-earth-free CoFeB/MgO magnetic tunnel junctions (MTJs), a material system widely adopted in spin-transf…
Challenges and opportunities in orbitronics
Shunsuke Fukami, Kyung-Jin Lee, Mathias Kläui
The spin of the electron has been a key enabler to realize spintronics devices that harness the spin degree of freedom beyond conventional charge-based electronics. In addition to…
Dynamical control of random telegraph noise in magnetic tunnel junctions
Mehrdad Elyasi, Shun Kanai, Hideo Ohno +2
Faster random telegraph noise (RTN) in magnetic tunnel junctions (MTJs) would be beneficial for probabilistic computing applications. However, the interactions between the macrospi…
Interfacial Dzyaloshinskii-Moriya interaction in nonmagnetic/noncollinear-antiferromagnetic bilayers
Yuta Yamane, Yasufumi Araki, Shunsuke Fukami
We study Dzyaloshinskii-Moriya interaction (DMI) appearing at the interface of a nonmagnetic/noncollinear-antiferromagnetic bilayer. DMI is an antisymmetric exchange interaction be…
Electrically Tunable Picosecond-scale Octupole Fluctuations in Chiral Antiferromagnets
Shiva T. Konakanchi, Sagnik Banerjee, Mohammad M. Rahman +4
We present a theory for the relaxation time of the octupole order parameter in nanoscale chiral antiferromagnets (AFMs) coupled to thermal baths and spin injection sources. Using s…
Effect of nonlinear magnon interactions on the stochastic magnetization switching
Mehrdad Elyasi, Shun Kanai, Hideo Ohno +2
Telegraph noise caused by frequent switching of the magnetization in small magnetic devices has become a useful resource for probabilistic computing. Conventional theories have bee…
Voltage-insensitive stochastic magnetic tunnel junctions with double free layers
Rikuto Ota, Keito Kobayashi, Keisuke Hayakawa +4
Stochastic magnetic tunnel junctions (s-MTJ) is a promising component of probabilistic bit (p-bit), which plays a pivotal role in probabilistic computers. For a standard cell struc…
