However, literature reports pertaining to the study of nano-crystalline thin films are less abundant. Thin films of Fe40Ni38B18Mo4 were deposited on glass substrates under a high vacuum of approximate to 10(-6) Torr by employing resistive heating. They were annealed at various temperatures ranging from 373 to 773K based on differential scanning calorimetric studies carried out on the ribbons. The magnetic characteristics were investigated using vibrating sample magnetometry. Morphological characterizations were carried out using atomic force microscopy (AFM), and magnetic force microscopy (MFM) imaging is used to study the domain characteristics. The variation of magnetic properties with thermal annealing is also investigated. From AFM and MFM images it can be inferred that the crystallization temperature of the as-prepared films are lower than their bulk counterparts. Also there is a progressive evolution of coercivity up to 573 K, which is an indication of the lowering of nano-crystallization temperature in thin films. The variation of coercivity with the structural evolution of the thin films with annealing is discussed and a plausible explanation is provided using the modified random anisotropy model.</p>1 aHysen, T.1 aDeepa, S.1 aSaravanan, S.1 aRamanujan, R., V.1 aAvasthi, D., K.1 aJoy, Pattayil, Alias1 aKulkarni, S., D1 aAnantharaman, Maliemadom, R.  uhttps://library.ncl.res.in/content/effect-thermal-annealing-fe40ni38b18mo4-thin-films-modified-herzer-model-magnetic-001467nas a2200205   4500008004100000022001400041245006400055210006200119260012500181300001100306490000700317520072400324100001901048700001801067700001601085700002001101700002401121700001801145856009801163       2008                        eng d  a0003-695100aAu-ZnO: a tunable localized surface plasmonic nanocomposite0 aAuZnO a tunable localized surface plasmonic nanocomposite  aCIRCULATION & FULFILLMENT DIV, 2 HUNTINGTON QUADRANGLE, STE 1 N O 1, MELVILLE, NY 11747-4501 USAbAMER INST PHYSICScJAN  a0431070 v923 a<p>In this letter, we report the thermal processing controlled tunability of localized surface plasmon resonance (LSPR) of Au nanoparticles embedded in ZnO matrix. Au-ZnO nanocomposite films were prepared by atom beam cosputtering and were annealed from 200 to 600 degrees C in Ar. A regular redshift similar to 110 nm (from 505 to 615 nm) in LSPR peak with increase in annealing temperature up to 600 degrees C is observed. Transmission electron microscopy results confirm the formation of Au nanoparticles supported by ZnO nanorods at annealing temperature of 600 degrees C. The Au-ZnO nanocomposite exhibits significant enhancement in the Raman signal for C(70) molecules.

Arrays of well-aligned ZnO nanorods of uniform diameter have been synthesized on the Si substrate precoated with Au, using a simple electron beam evaporation method without the flow of any carrier gas. Scanning electron microscopy and atomic force microscopy characterizations show that as-grown nanorods are well aligned and uniform in diameter. X-ray diffraction measurements and clear lattice fringes in high-resolution transmission electron microscopy image show the growth of good quality polycrystalline hexagonal ZnO nanorods and a &lt; 0 0 2 &gt; growth direction. The polarization-dependent studies of near edge x-ray absorption fine structure (NEXAFS) are performed to investigate the electronic structure of the zinc and oxygen ions. The analysis of NEXAFS spectra at different angles of incidence of photon flux indicates the formation of ZnO nanorods having anisotropic behaviour of O and Zn states. The photoluminescence spectrum exhibits strong ultraviolet emission at 385 nm and the UV-visible spectrum also shows a band-gap transition around 390 nm indicating the good quality of nanorods. The catalytic growth mechanism of the ZnO nanorods is discussed on the basis of experimental results in this work.</p>1 aAgarwal, Dinesh, C.1 aChauhan, R., S.1 aAvasthi, D., K.1 aSulania, I.1 aKabiraj, D.1 aThakur, P.1 aChae, K., H.1 aChawla, Amit1 aChandra, Ramesh1 aOgale, S., B.1 aPellegrini, G.1 aMazzoldi, P.  uhttps://library.ncl.res.in/content/vls-growth-and-characterizations-dense-zno-nanorods-grown-e-beam-process-001338nas a2200253   4500008004100000022001400041245011100055210006900166260007300235300001200308490000800320520042000328653001500748653002400763653002000787653002300807100002700830700002400857700002100881700002000902700001300922700002200935856012700957       2012                        eng d  a0168-583X00aSwift heavy ion induced formation of Al/polymer composite layer for low thermal emissivity in the IR range0 aSwift heavy ion induced formation of Alpolymer composite layer f  aPO BOX 211, 1000 AE AMSTERDAM, NETHERLANDSbELSEVIER SCIENCE BVcSEP  a135-1400 v2873 a<p>Composites of polymers with aluminium were formed by swift high energy ions of 150 MeV, which are used as low thermal emissivity materials for infrared wavelengths between 8-14 mu m.
