We simulated the generation and propagation of spin waves (SWs) using two excitation methods, namely, magnetic field voltage induced strain. A fully coupled non-linear magnetoelastic model, combining Landau–Lifshitz-Gilbert with elastodynamic equations, is used to study characteristics SWs in materials. Simulation results show that for frequencies above ferromagnetic resonance (FMR), excited by strain propagate over longer distances compared field. In addition, mediated exhibit loss...
Composite multiferroic systems, consisting of a piezoelectric substrate coupled with ferromagnetic thin film, are great interest from technological point view because they offer path toward the development ultralow power magnetoelectric devices. The key aspect those systems is possibility to control magnetization via an electric field, relying on magneto-elastic coupling at interface between and components. Accordingly, direct measurement both electrically induced magnetic behavior...
Abstract Strain-coupled multiferroic heterostructures provide a path to energy-efficient, voltage-controlled magnetic nanoscale devices, region where current-based methods of control suffer from Ohmic dissipation. Growing interest in highly magnetoelastic materials, such as Terfenol-D, prompts more accurate understanding their magnetization behavior. To address this need, we simulate the strain-induced change with two modeling methods: commonly used unidirectional model and recently...
Narrowband ultraviolet (UV) photodetectors are highly desired in multiple areas. Photodetectors based on organic-inorganic nanocomposites offer high sensitivity, widely adjustable response range, light weight, and low-temperature solution processibility. However, the broad absorption range of organic inorganic semiconductor materials makes it difficult to achieve a narrowband detection feature for nanocomposite photodetectors. In this work, thin films containing wide band gap conjugated...
Ferromagnetic resonance and spin waves have been used in miniaturized devices for rf microwave applications, but large magnetic bias fields are required the high frequencies at which most satellites operate, example. Exploiting perpendicular standing an innovative way, authors excite spin-wave above 20 GHz with below 100 Oe, can be realized small, lightweight permanent magnets, or electromagnets current sources that would not require cooling.
Development and application of physically separated references for aqueous 1H DOSY diffusion coefficient-formula weight (D-FW) correlation analysis is reported. Commercially available biological buffers (Tris HEPES) a water-soluble alcohol (tert-butanol) were used as Ru Mn complex in D2O. This extension D-FW expands its applicability to wide variety molecules or metal complexes, with particular green chemistry.
Organic-inorganic hybrid ultraviolet photodetectors with tunable spectral response are desirable for many different applications.

Designing and implementing means of locally trapping magnetic beads understanding the factors underlying bead capture force are important steps toward advancing capture-release process particles for biological applications. In particular, capturing magnetically labeled cells using microstructures with perpendicular anisotropy (PMA) will enable an approach to cell manipulation emerging lab-on-a-chip devices. Here, a Co (0.2 nm)/Ni (0.4 nm) multilayered structure was designed exhibit strong...
