Spintronic Bayesian Hardware Driven by Stochastic Magnetic Domain Wall Dynamics

Advanced Science, EarlyView.
Magnetic Probabilistic Computing (MPC) utilizes intrinsic stochastic dynamics in domain walls to establish a hardware foundation for uncertainty‐aware artificial intelligence. Thermally driven domain‐wall fluctuations, voltage‐controlled magnetic anisotropy, and TMR readout enable fully electrical, tunable probabilistic inference.

Grain boundary effects on magnetotransport in bi-epitaxial films of La$_{0.7}$Sr$_{0.3}$MnO$_3$

, 2000
The low field magnetotransport of La$_{0.7}$Sr$_{0.3}$MnO$_3$ (LSMO) films grown on SrTiO$_3$ substrates has been investigated. A high qualtity LSMO film exhibits anisotropic magnetoresistance (AMR) and a peak in the magnetoresistance close to the Curie ...

Nonrelativistic Spin Current Generated Unconventional Spin Hall Magnetoresistance in Altermagnetic RuO2

Advanced Science, EarlyView.
It is reported that the unconventional spin Hall magnetoresistance generated from nonrelativistic spin currents in RuO2 is capable of accurately detecting spin current polarization and disentangling the T̂$\hat{T}$‐odd and T̂$\hat{T}$‐even components of a spin current.

Tunneling magnetoresistance in nanogranular La1-xSrxMnO3 (x∼0.5)

AIP Advances, 2017
Electric transport and magnetic studies were performed on the La1-xSrxMnO3 (x=0.45-0.55) perovskite manganites. The main focus was given to the nanogranular ceramics of average x=0.47 composition, compacted by spark plasma sintering of molten salt ...

Tunneling Anisotropic Magnetoresistance in Ferroelectric Tunnel Junctions

Physical Review Applied, 2019
Using a simple quantum-mechanical model, we explore a tunneling anisotropic magnetoresistance (TAMR) effect in ferroelectric tunnel junctions (FTJs) with a ferromagnetic electrode and a ferroelectric barrier layer, which spontaneous polarization gives rise to the Rashba and Dresselhaus spin-orbit coupling (SOC).

Spin‐Selective Interface Engineering in Oxide–Ferromagnetic Junctions via Atomic‐Scale Oxygen Control

Advanced Science, EarlyView.
We show that interfacial oxygen at the MgO/Fe interface can be transformed from an uncontrolled variable into a tunable design parameter for spintronic junctions. Momentum microscopy provides direct access to the momentum‐ and spin‐resolved electronic structure beneath the insulating MgO layers, revealing how oxygen intercalation reshapes buried Fe ...
