Heterostructures consisting of superconducting MoRe electrodes with a critical temperature about 9 K and a silicon film with a thickness of several dozens of nm (sandwiched between them) were fabricated. The silicon layer was doped by tungsten with various atomic concentrations. By using an atomic force microscope we have investigated a relief of the every layer of the fabricated Josephson junction, as a result it has been demonstrated a possibility to observe a formation of the cluster structure of tungsten in the silicon layer in the Josephson junction barrier on a nano-sized level. Measured I-V curves of these junctions demonstrate that the well-known parameter of these junctions (named the characteristic voltage) has record values. The observation is explained as the fingerprint of “open” channels in the charge transmission due to resonance-percolating trajectories inside the strongly inhomogeneous silicon interlayer with metallic nanoclusters.","PeriodicalId":6516,"journal":{"name":"2017 IEEE 7th International Conference Nanomaterials: Application & Properties (NAP)","volume":"197 1","pages":"04NESP07-1-04NESP07-4"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83098327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This particle is supposed to be placed into a viscous liquid and excited by an external alternating magnetic field. Two modes of motion were studied analytically in the noise-free approximation. Within the first mode, both the nanoparticle magnetic moment and easy axis perform small oscillations around the initial position. The oscillation amplitudes were obtained in the harmonic approximation. Just the magnetic moment demonstrates the resonant behaviour that causes the main features of the oscillation mode. Within the second mode, the nanoparticle magnetic moment and easy axis are rotated synchronously. In this case we obtained the system of algebraic equations, where the precession and lag angles of the magnetic moment and easy axis are the solutions of these equations. The results obtained allow to make an analysis of the mechanism of ferrofluids heating by alternating magnetic fields.","PeriodicalId":6516,"journal":{"name":"2017 IEEE 7th International Conference Nanomaterials: Application & Properties (NAP)","volume":"18 1","pages":"02MFPM09-1-02MFPM09-4"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86616865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A thin coating of TiAlN was deposited on R6M5 high-speed steel using an curent magnetron sputtering (DCMS) process.

Complete substrates properties damping was achieved at nickel thicknesses of about 40, 90 and 20 nm for NaCl, Si, and GaAs, respectively. The contact angle θ change has been explained by the heterogeneity of the wettable surface.
