Spin orbit torque non-volatile flip-flop for high speed and low energy applications
, 2014 International audienceA novel nonvolatile flip-flop based on spin-orbit torque magnetic tunnel junctions (SOT-MTJs) is proposed for fast and ultralow energy applications. A case study of this nonvolatile flip-flop is considered.

Controllable spin-transfer torque on an antiferromagnet in a dual spin-valve [PDF]
, 2011 We consider current-induced spin-transfer torque on an antiferromagnet (AFM) in a dual spin-valve setup. It is demonstrated that a net magnetization may be induced in the AFM by partially or completely aligning the sublattice magnetizations via a current-

High write endurance up to 1012 cycles in a spin current-type magnetic memory array
AIP Advances, 2019 We demonstrated high write endurance of up to 1012 cycles with a pulse write current of 10 ns in a spin current-type (SC) single magnetic tunnel junction (MTJ) element and 8×8 memory array.

Atomic‐Scale Detection of Néel Vector Switching in the Single‐Layer A‐Type Antiferromagnet Cr2S3‐2D
Advanced Materials, EarlyView.Interfacial electron donation from graphene redistributes charge within single‐layer Cr2S3‐2D, preferentially accumulating at the lower Cr/S plane. The resulting minute magnetic imbalance lifts the equivalence of the two magnetic sublayers, enabling atomic‐resolution identification and field‐induced control of Néel‐vector states in a two‐dimensional A ...

Spin transfer torque enhancement in dual spin valves in the ballistic regime
, 2011 The spin transfer torque in an all-metal dual spin valve, in which two antiparallel-aligned pinned ferromagnetic layers are on the two sides of a free ferromagnetic layer with two thin normal metal spacers in between, is studied in the ballistic regime ...

Spin-torque switching of a nano-magnet using giant spin hall effect
AIP Advances, 2015 The Giant Spin Hall Effect(GSHE) in metals with high spin-orbit coupling is an efficient way to convert charge currents to spin currents, making it well-suited for writing information into magnets in non-volatile magnetic memory as well as spin-logic ...

Advanced Materials, EarlyView.Crystal orientation and domain engineering enable bulk mirror symmetry breaking in Bi1−xSbx, resulting in ultralow current‐induced switching of perpendicular magnetization without an external field. By exploiting single‐domain Bi1−xSbx (012), the authors demonstrate an out‐of‐plane spin Hall conductivity of ∼1.12×105ℏ2eΩ−1m−1$ \sim \!1.12 \ensuremath ...

Fast Hydrogel Micro‐Actuators Driven by Electric Fields
Advanced Materials, EarlyView.We report the fabrication of chemically programmable electroactuating microstructures through the first integration of two‐photon polymerization with electrically actuated gelatin methacrylate‐based hydrogels. By tailoring the charge of the polymer network, we demonstrate programmable polarity‐dependent bending, enabling microstructures that ...
