Giant negative magnetoresistance in Manganese-substituted Zinc Oxide

, 2015
We report a large negative magnetoresistance in Manganese-substituted Zinc Oxide thin films. This anomalous effect was found to appear in oxygen-deficient films and to increase with the concentration of Manganese.

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

Advanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Decoupled Spin Hall Voltage Readout for Domain‐Wall Synapses in Embedded Neuromorphic Computing

Advanced Intelligent Systems, EarlyView.
Magnetic domain‐wall synapses provide nonvolatile multilevel states with linear, symmetric weight updates, making them attractive for neuromorphic hardware. However, DW MTJ readout has magnetoresistance‐limited dynamic range, while anomalous‐Hall readout suffers from weak voltage output and read/write coupling.

Wide‐range and high‐resolution Young's modulus sensing enabled by a complementary indentation‐protrusion architecture

FlexMat, EarlyView.
A tactile sensor integrating indentation and protrusion sensing within a single platform enables accurate perception of object Young's modulus. This complementary architecture expands the detectable Young's modulus range to 25.8–2639.2 kPa and achieves an object recognition accuracy of 94.27%, outperforming indentation‐only (84.59%) and protrusion‐only
