Abstract Crystal structure exerts dominant influence on the microwave dielectric performance enabling satisfying demands for 5G communication system. In this study, Ti‐doped Li 3 Mg 2 Nb 1‐x Ti x O 6‐x/2 ( = 0.0‐0.1) ceramics were prepared by solid‐state reaction procedure. refinement and microstructure analysis indicate pure phase with orthorhombic homogeneous grain size (~14 μm). The relative permittivity was affected density, cell volume, polarizability. Q × f value dominated Nb‐O bond...
Abstract Composition and structure play dominant roles in realizing the microwave dielectric properties that are necessary for ever‐increasing demands of Internet Things related communication technologies. In present study, substitution Ta 5+ Li 3 Mg 2 Nb 1− x O 6 ceramics its effect on structural characteristics performances is systematically studied. All substituted compositions were determined to be pure phase orthorhombic Li3Mg2NbO6 space group Fddd . Furthermore, a NbO octahedral...
Bistability, a universal phenomenon found in diverse fields such as biology, chemistry, and physics, describes scenario which system has two stable equilibrium states resets to one of the states. The ability switch between these is basis for wide range applications, particularly memory logic operations. Here, we present approach achieve bistable switching magnonics, field processing data using spin waves. A pronounced window observed 1 μm magnonic conduit under an external rf drive....
Yttrium iron garnet (YIG) is a material with unique properties that make it very attractive for use in microwave applications, such as frequency-selective limiters and logic processing. However, the decay of spin wave's amplitude propagates curbs YIG practical applications. To surmount this limitation, study surface currents topological insulator are used to enhance spin-wave adjacent YIG. In addition, interesting magnons observed investigated, advance spintronics.
Abstract For generating or detecting spin currents without ferromagnetic materials in spintronic devices, nonmagnetic with large Hall angles would elicit extreme interest. A giant inverse effect (ISHE) Pt doped 8% Bi by composition is demonstrated. From a combination of resonance, pumping, and ISHE experiments, current found induced an yttrium iron garnet/Pt 0.92 0.08 bilayer. The diffusion length angle the alloy are λ SD = 3.3 ± 0.1 nm θ SH 0.106 0.005, respectively. In spin–charge...
Selectivity and uniformity are the stuck issues for NbO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><i>x</i></sub> –based selectors applied in memory arrays. In this letter, we experimentally demonstrated that selector through Al-doping had significant improvement of selectivity (250%) (from 4% to 1%). To understand physical mechanism, thermoelectric coupling model was employed. It simulatively illustrated lower OFF current higher were...
Binary metal oxide materials, such as nickel oxide, are widely used in flexible resistive variable memory devices due to advantages their easily controllable material composition, simple structural and good compatibility between manufacturing processes complementary processes. In this work, a solution combustion method was employed prepare NiOx thin films for use switching layer of resistance random-access memory. The formation temperature the RRAM device kept low 175 °C, making compatible...

The metal-to-insulator transition (MIT) in niobium oxide (NbO2) regulated by oxygen vacancies (VOs) is of limited understanding. Here, we systematically investigate the reversible VOs-MIT, focusing on structural, polaron, electronic, and chemical bonding characteristics. Interestingly, VOs modulate Nb–Nb dimers renormalize charges small polarons. strongly perturb high-symmetry metal phase split d∥ orbitals while only broadening local insulating phase. Driven cooperative Mott–Peierls...
