Journal ArticleDOI
A magnetic synapse: multilevel spin-torque memristor with perpendicular anisotropy.
Steven Lequeux,Joao Sampaio,Vincent Cros,Kay Yakushiji,Akio Fukushima,Rie Matsumoto,Hitoshi Kubota,Shinji Yuasa,Julie Grollier +8 more
TL;DR: The first experimental achievement of a multilevel memristor compatible with spin-torque magnetic random access memories is shown and it is demonstrated that the magnetic synapse has a large number of intermediate resistance states, sufficient for neural computation.
Journal ArticleDOI
Vertical-current-induced domain-wall motion in MgO-based magnetic tunnel junctions with low current densities
André Chanthbouala,Rie Matsumoto,Julie Grollier,Vincent Cros,Abdelmadjid Anane,Albert Fert,Alexey Vasilyevitch Khvalkovskiy,K. A. Zvezdin,Kazumasa Nishimura,Yoshinori Nagamine,H. Maehara,K. Tsunekawa,Akio Fukushima,Shinji Yuasa +13 more
TL;DR: In this paper, a device that uses a novel geometry for injecting electrical currents into the sample is shown to work with current densities that are two orders of magnitude lower than in previous approaches.
Journal ArticleDOI
Tunneling spectra of sputter-deposited CoFeB/MgO/CoFeB magnetic tunnel junctions showing giant tunneling magnetoresistance effect
Rie Matsumoto,Yusuke Hamada,Masaki Mizuguchi,Masashi Shiraishi,H. Maehara,Koji Tsunekawa,David D. Djayaprawira,Naoki Watanabe,Yoshinari Kurosaki,Taro Nagahama,Akio Fukushima,Hitoshi Kubota,Shinji Yuasa,Shinji Yuasa,Yoshishige Suzuki,Yoshishige Suzuki +15 more
TL;DR: In this article, the authors measured differential tunneling conductance (d I/d V, d 2 I /d V 2 ) spectra of spin-valve-type magnetic tunnel junctions (MTJs) with a MgO(001) tunnel barrier layer and amorphous CoFeB ferromagnetic electrodes that show 315% magnetoresistance (MR) ratio at 4.3
Journal ArticleDOI
Voltage-Induced Magnetic Anisotropy Changes in an Ultrathin FeB Layer Sandwiched between Two MgO Layers
Takayuki Nozaki,Kay Yakushiji,Shingo Tamaru,Masaki Sekine,Rie Matsumoto,Makoto Konoto,Hitoshi Kubota,Akio Fukushima,Shinji Yuasa +8 more
TL;DR: In this paper, the effect of voltage on the perpendicular magnetic anisotropy in an ultrathin Fe80B20 layer sandwiched between two MgO barrier layers with different thicknesses was investigated.
Journal ArticleDOI
Noise-Enhanced Synchronization of Stochastic Magnetic Oscillators
Nicolas Locatelli,Alice Mizrahi,Artur Difini Accioly,Artur Difini Accioly,Rie Matsumoto,Akio Fukushima,Hitoshi Kubota,Shinji Yuasa,Vincent Cros,Luis Gustavo Pereira,Damien Querlioz,Joo-Von Kim,Julie Grollier +12 more
TL;DR: It is shown that injection-locking in a stochastic magnetic oscillator with superparamagnetic free layer is robust and leads to a drastic reduction in the phase diffusion of the Stochastic oscillator, despite the presence of a frequency mismatch between the oscillator and the excitation.
