Magnetoresistance and Annealing Behaviors of Particulate Co–Au Nanocomposites
Co core Au shell nanoparticles, stabilized with a sulfobetaine surfactant, were fabricated from a displacement reaction of Au 3+ with Co nanoparticles and compressed into a granular composite. TheExpand
Tantalum oxide coatings as candidate environmental barriers
Tantalum (Ta) oxide, due to its high-temperature capabilities and thermal expansion coefficient similar to silicon nitride, is a promising candidate for environmental barriers for silicon (Si)Expand
Superconducting properties of MgCNi3 films
(Received 28 April 2003; published 3 July 2003) We report the magnetotransport properties of thin polycrystalline films of the recently discovered nonoxide perovskite superconductor MgCNi 3 . CNi 3Expand
Scaling behavior of the critical current density in Mg C Ni 3 microfibers
We present transport critical current measurements on microfibers consisting of a $80\text{\ensuremath{-}}\mathrm{nm}$ thick layer of polycrystalline $\mathrm{Mg}\mathrm{C}{\mathrm{Ni}}_{3}$Expand
Low-temperature susceptibility of the noncentrosymmetric superconductor CePt3Si.
Though transport measurements show a relatively high upper critical field B(c2) approximately 4-5 T, the low-temperature susceptibility chi(') is quite fragile to the applied field, with chi (') diminishing rapidly in fields of a few kG. Expand
Giant Magnetoresistance Behavior of an Iron/Carbonized Polyurethane Nanocomposite
This letter describes the magnetoresistance (MR) behavior of the heat treated polyurethane composites reinforced with iron nanoparticles. The flexible nanocomposites were fabricated by theExpand
Flexible high-loading particle-reinforced polyurethane magnetic nanocomposite fabrication through particle-surface-initiated polymerization
Flexible high-loading nanoparticle-reinforced polyurethane magnetic nanocomposites fabricated by the surface-initiated polymerization (SIP) method are reported. Extensive field emission scanningExpand
Synthesis, Structure, and Magneto-transport of LnNi1-xSb2 (Ln = Y, Gd−Er)
Single crystals of the ternary antimonides LnNi1-xSb2 (Ln = Y, Gd−Er; x ∼ 0.4) have been grown from antimony flux. X-ray diffraction experiments reveal that these compounds crystallize in theExpand
Magnetic and electromagnetic evaluation of the magnetic nanoparticle filled polyurethane nanocomposites
The magnetic and electromagnetic wave absorption behavior of a flexible iron-nanoparticle reinforced polyurethane nanocomposite is reported. Surface-initiated-polymerization (SIP) method was utilizedExpand
High-Pressure Synthesis, Crystal Structure Determination, and a Ca Substitution Study of the Metallic Rhodium Oxide NaRh2O4
The sodium rhodate NaRh2O4 was synthesized for the first time and characterized by neutron and X-ray diffraction studies and measurements of magnetic susceptibility, specific heat, electricalExpand
