On the basis of semiconductor-ferromagnet GaAs-Fe3Si core-shell nanowires (Nws) we compare the facilities of magnetic Nw ensemble measurements by superconducting quantum interference device magnetometry versus investigations on single Nws by magnetic

Multiferroics, materials in which both magnetic and electric fields can induce each other, resulting in a magnetoelectric response, have been attracting increasing attention, although the induced magnetic susceptibility and dielectric constant are us

We demonstrate the growth of crystalline Co2FeSi/MgO/GaAs(0 0 1) hybrid structures of different MgO interlayer thicknessess by molecular beam epitaxy. The MgO layer thickness was verified by X-ray reflectivity measurements and high-resolution transmi

We studied metastable $\ensuremath{\alpha}\text{\ensuremath{-}}\mathrm{Fe}{\mathrm{Ge}}_{2}$, a layered tetragonal material, embedded as a spacer layer in spin valve structures with ferromagnetic ${\mathrm{Fe}}_{3}\mathrm{Si}$ and ${\mathrm{Co}}_{2}\

Nonreciprocal propagation of sound, that is, the different transmission of acoustic waves traveling in opposite directions, is a challenging requirement for the realization of devices such as acoustic isolators and circulators. Here, we demonstrate e

Bi2Te3 is deposited by hot wall epitaxy in an attempt to form nanosheets on epitaxially-grown ferromagnetic layers of Fe, Fe3Si and Co2FeSi. Bi2Te3 reacts strongly with pure Fe, producing FeTe2. The reaction is suppressed for silicides Fe3Si and Co2F

We demonstrate first measurements of successful spin generation in crystalline ${\mathrm{Co}}_{2}\mathrm{FeSi}$/MgO/GaAs hybrid structures grown by molecular-beam epitaxy (MBE) with different MgO interlayer thicknesses. Using nonlocal spin valve and

The structure and dynamical properties of the ${\mathrm{Fe}}_{3}\mathrm{Si}/\mathrm{GaAs}(001)$ interface are investigated by density functional theory and nuclear inelastic scattering measurements. The stability of four different atomic configuratio
We investigate the formation of lattice matched single-crystalline Fe3Si/GaAs(001) ferromagnet/semiconductor hybrid structures by Volmer–Weber island growth, starting from the epitaxial growth of isolated Fe3Si islands up to the formation of contin
