We observed unexpected resonant response in [Fe/Cr]10 multilayers epitaxially grown on MgO(100) substrates which exists only when both ac current and dc magnetic field are simultaneously applied. The magnitude of the resonances is determined by the multilayer magnetization proving their intrinsic character. The reduction of interface epitaxy leads to nonlinear dependence of the magnitude of res...

We study experimentally the current-driven magnetic excitations in symmetric Co/Cu/Co nanopillars. In contrast with all the previous observations where the current of only one polarity is capable of exciting a multilayer system saturated by an externally applied magnetic field, we observe that both polarities of the applied current trigger excitations in a symmetric multilayer. This may indicat...

The application of colloidal nanocrystals in various devices requires their assembly into well-defined mono- or multilayers. We explore the possibilities of the Langmuir-Schaefer technique to make such layers, using CdSe quantum dots as a model system. The layer quality is assessed using atomic force microscopy, transmission electron microscopy, and UV-vis absorption spectroscopy. For hydrophob...

We report a tunable magnetoresistance (MR) behavior in suspended graphitic multilayers through point-defect engineering by ion implantation. We find that ion implantation drastically changes the MR behavior: the linear positive MR in pure graphitic multilayers transforms into a negative MR after introducing significant shortrange disorders (implanted boron or carbon atoms), consistent with rece...

In this study, we report on phase formation and microstructure evolution in multiscale magnetron sputtered Ru/Al multilayers upon thermal annealing vacuum at slow heating rates of 10 K/min. By specifically adjusting the design as-deposited multilayers, certain desired phases can be tuned. We demonstrate that synthesis single RuAl thin films is possible a very controlled manner solid state only ...

Magnetoimpedance (MI) biosensors for the detection of in-tissue incorporated magnetic nanoparticles are a subject special interest. The possibility ferrogel samples mimicking natural tissues with was proven previously symmetric MI thin-film multilayers. In this work, in order to describe effect non-symmetric multilayered elements covered by layer we propose an electromagnetic model based on sol...

Successive evaporations of two correctly choosen elements permit now to obtain high efficient Bragg reflectors in X-UV where until now the grazing incidence optics was the only one solution. The potentialities of the X-U.V range for imaging and microscopy have been clearly underlined since the fifties (1) but pratical difficulties have damped a real development, not only in the field of X-rays ...

We measured the anisotropy of Magnetic Compton profiles (MCP) in Fe/MgO multilayers and compared it with band structure calculations. At interface, |m| = 1 state minority is suppressed, which turn promotes spin-polarized occupation state. Fe/FeO interface intentionally oxidized multilayers, occupations magnetic quantum number are almost equal (spherical) majority band, therefore, spin-polarizat...

Near infrared (NIR) upconverters only emit at a single visible wavelength; coating them with quantum dot multilayers allows the emission wavelength to be tuned across the visible spectrum.
