Electric-field-induced dipole reorientation characteristics in paraelectric KTN crystals
Local dipoles significantly influence the properties of paraelectric perovskites. Potassium tantalate niobate (KTa1−xNbxO3, abbreviated as KTN) is a perovskite with excellent electro-optic and piezoel...
Magnetic-field-dependent ultrafast carrier dynamics and spin–lattice interaction in Au nanopillar/La0.67Sr0.33MnO3 film composites
We investigate the carrier and spin dynamics of nanocomposite thin films with Au nanopillars vertically aligned in the La0.67Sr0.33MnO3 matrix using ultrafast optical spectroscopy at 10 K in a magneti...
Multi-parameter assessment of osteoporosis based on x-ray induced acoustic computed tomography
X-ray induced acoustic computed tomography (XACT) reconstructed the internal x-ray absorption distribution of bone tissue through the ultrasound generation by the thermoelastic effect. In this paper,...
Defect spectroscopy of MBE-grown GaAs0.51Sb0.49 pin infrared detectors on InP substrates
The deep level defect spectrum within GaAs0.51Sb0.49 photodiode absorber layers, grown by molecular beam epitaxy (MBE) and designed to operate at a wavelength of 1.55 μm, is revealed and characterized...
Magnetoelectric composite engineered dielectric energy storage in flexible film capacitor devices
In contrast to traditional dielectric capacitors limited to electrical energy storage, this work proposes a magnetoelectric composite film enabling dual-field energy conversion and storage in both mag...
Size dependence of the properties of synthetic-antiferromagnet-based stochastic magnetic tunnel junctions for probabilistic computing
Stochastic magnetic tunnel junctions (s-MTJs) are core components for spintronics-based probabilistic computing, offering promising routes toward energy-efficient unconventional computing. A synthetic...
Bidirectional spin-filtering effects in altermagnetic spin field-effect transistors
Realizing ideal and bidirectionally controllable spin-filtering effects in a single material is essential for the advancement of short-channel spin field-effect transistors (spin-FETs). Such advanceme...
YbCo2: Large magnetic entropy change per volume in Yb-based metallic magnetic refrigerants for sub-Kelvin temperature
A Yb-based intermetallic compound YbCo2 exhibiting a magnetic-field-induced order is known to show a giant specific heat divided by temperature, C/T∼ 6.5 J/K2 mol, around 0.3 K. We investigate the pot...
Rockseline lead chalcogenides: An alternative class of high-performance thermoelectric materials
Lead chalcogenides crystallizing in NaCl-type structure are known as excellent thermoelectric materials. Yet, they have suffered the long-standing issue of performance imbalance between n-type and p-t...
Heat-assisted ferroelectric reading for high-speed ferroelectric probe data storage
We propose a heat-assisted ferroelectric reading method that increases read speed while maintaining the polarization retention characteristics of ultrahigh-density ferroelectric data storage, namely,...
