Feature Disentangling and Combination Implemented by Spin–Orbit Torque Magnetic Tunnel Junctions

Advanced Intelligent Systems, EarlyView.
Spin–orbit torque magnetic tunnel junctions (SOT‐MTJs) enable efficient feature disentangling and integration in image data. A proposed algorithm leverages SOT‐MTJs as true random number generators to disentangle and recombine features in real time, with experimental validation on emoji and facial datasets.

Magnetron Sputtering Synthesis of La‐Doped BiFeO3 Thin Films and Enhanced Exchange Bias in CoFeB/Bi1‐xLaxFeO3 Heterostructures

Advanced Physics Research, EarlyView.
This study explores the epitaxial growth of high‐quality La‐doped BiFeO3 (BLFO) thin films at 550 °C using magnetron sputtering. The films exhibit good ferroelectric properties and low leakage current. A BLFO/CoFeB heterostructure is constructed, achieving an exchange bias field exceeding the coercive field at room temperature.

Surface Properties of CeB6 and Challenges in Surface Preparation Revealed by Scanning Tunneling Microscopy

Advanced Physics Research, EarlyView.
The investigation of the Kondo lattice system CeB6${\rm CeB}_6$ by highly surface sensitive techniques is hampered by difficulties in preparing well‐ordered, atomically flat surfaces. The richness of possible surface terminations and their impact on spectroscopic STM results are discussed.

Effect of Fe Doping on the Structural, Morphological, Optical, and Magnetic Properties of Ca2InTaO6 Double Perovskite

physica status solidi (b), EarlyView.
Fe‐doped Ca2InTaO6 double perovskites are synthesized via solid‐state reaction and systematically investigated. Rietveld refinement confirms orthorhombic Pbnm structure, while optical studies reveal a bandgap narrowing from 3.31 to 2.84 eV. Photoluminescence spectra exhibit strong red emission at 671 nm with optimal intensity at 10 mol% Fe ...

Magnetic and Electronic Inhomogeneity in Sm_1−xEu_xB₆

Condensed Matter
While SmB6 attracts attention as a possible topological Kondo insulator, EuB6 is known to host magnetic polarons that give rise to large magnetoresistive effects above its ferromagnetic order transition. Here, we investigate single crystals of Sm1−xEuxB6

Structural and Transport Properties of Thick and Thin Cr2AlC Films

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
This study compares structural and transport properties of Cr2AlC thin films (50 and 500 nm) systematically disordered by ion irradiation. Columnar grain growth is observed only in 500 nm films, while both films exhibit a weak fiber texture. Kondo scattering from displaced Cr atoms leads to a resistivity upturn, with distinct magnetoresistance in each ...
