    The role of NiAl underlayers in longitudinal thin-film recording media (1997)

    Notes: Longitudinal recording media made with chromium and with nickel-aluminum underlayers are compared. NiAl films have smaller grains and random crystallographic orientation, while Cr films have larger grains and either a {110} or a {200} preferred orientation depending on the deposition conditions. Cobalt alloy films grown on NiAl have nearly random crystallographic orientation and significant c-axis out-of-plane component, and lower hysteresis loop squareness and coercivity than films made on a heated Cr underlayer. NiAl-underlayer media do not exhibit in-plane magnetic anisotropy induced by the substrate texture lines. CoCrTaPt/Cr/NiAl media had higher overwrite than CoCrTaPt/Cr media due to higher coercive squareness and a sharper hysteresis loop closure. © 1997 American Institute of Physics.

    Notes: A low energy broad beam multipole ion source has been successfully developed at the Southwestern Institute of Physics, which can be used for both sputtering deposition and direct ion beam deposition. The extracted A+r beam current is 30–250 mA at a beam energy of 200–6000 eV. It has been used for sputtering deposition at the three beam synchronously mixing machine in Dalian University of Technology.

    The role of NiAl underlayers in longitudinal recording media (abstract) : The 41st annual conference on magnetism and magnetic materials (1997)

    Notes: NiAl has been proposed as a replacement for the Cr underlayer in longitudinal recording media.1 NiAl has a B2 ordered structure with a lattice parameter close to that of Cr. Hence the same epitaxial relationships that exist in CoCrPt/Cr could also exist in CoCrPt/NiAl. Although high coercivity media have been made using a NiAl underlayer, a detailed microstructural study of the CoCrPt/NiAl is lacking. We have investigated the crystal orientation and epitaxial relationships in CoCrPt/NiAl bilayers deposited by DCM sputtering at a range of deposition temperatures up to 250 °C and sputter rates of 0.5–10 nm/s. Samples were examined by high resolution transmission electron microscopy in cross section and plan view. None of the samples showed the (002) NiAl/(11¨20)Co orientation that would be expected by analogy to CoCrPt/Cr films deposited at high temperatures. The CoCrPt crystals in the CoCrPt/NiAl are oriented with their c axes at a range of angles to the film plane, accounting for the lower squareness (Sq) of the magnetic hysteresis loop compared to samples on Cr underlayers. There is no evidence of the "bicrystal" structure in CoCrPt/NiAl as is seen on films grown on Cr.2 Grain size in NiAl is smaller than in Cr giving a smaller grain size in the CoCrPt overlayer and potentially lower medium noise. However, coercivity of CoCrPt/NiAl is lower than CoCrPt/Cr. The coercivity increases as the NiAl film thickness increases, and this is believed to be caused by topographic isolation of the magnetic grains.3 Recording measurements on CoCrPt/NiAl and CoCrPt/Cr media show that noise is lower in isotropic media made on the NiAl underlayer compared to oriented media made on the Cr underlayer. The microstructural results will be compared with previously published results on NiAl underlayers and the utility of NiAl as an underlayer in high density media will be assessed. © 1997 American Institute of Physics.

    Notes: An 8.5 cm multipole ion source for an MM-2U neutral beam injector has been developed. The source is operated with a discharge current of more than 200 A. The saturation ion current at the plasma grid is 300 mA/cm2. A hydrogen ion current of 9 A has been obtained at an accel. voltage of 25 kV with 50 ms pulse duration. This article describes the experiment apparatus and the experimental results.

    Effects of processing conditions on negative bias temperature instability in metal-oxide-semiconductor structures (1988)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 52 (1988), S. 1344-1346

    ISSN: 1077-3118

    Topics: Physics
    Notes: Radiation from electron beam metallization has been found to result in damage to metal-oxide-semiconductor structures, which, when not properly annealed out, can lead to severe negative bias temperature instability (NBTI), even at room temperature. Similarly, rapid thermal annealing (RTA) after oxidation can result in significant room-temperature instability. The post-metal-annealing behavior of this RTA-induced instability depends on the high-temperature annealing ambient (Ar vs O2). Processing in O2 can also lead to significant NBTI; however, following such steps by an Ar anneal at the same temperature can negate the effect, and in some cases, lead to an overall reduction in NBTI. An electrical current flows during the stressing measurement and can be correlated with the development of oxide positive charge. This finding supports a model for charge buildup during NBT stressing in which holes from the Si substrate become trapped in intrinsic hole traps located within the oxide.

    Fermi-level effect on the interdiffusion of InAs and InGaAs quantum dots (2001)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 78 (2001), S. 3115-3117

    ISSN: 1077-3118

    Topics: Physics
    Notes: Data are presented on the Fermi level influence on interdiffusion in self-organized quantum dots. Modulation doping is used to place either electrons or holes in the quantum dots' zero-dimensional levels. The ground state emission energy and discrete level energy separations show that p-type modulation doping enhances the interdiffusion of the quantum dot material with its surrounding barriers, while n-type doping inhibits the interdiffusion. The results are consistent with the interdiffusion proceeding through interstitial crystal defects. © 2001 American Institute of Physics.

    Deposition of large area YBa2Cu3O7 superconducting films by laser scanning ablation (1993)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 63 (1993), S. 3370-3372

    ISSN: 1077-3118
    Source: AIP Digital Archive
    Topics: Physics
    Notes: A method of laser scanning ablation for producing large area YBa2Cu3O7 superconducting films is presented. Uniformly thick, large area YBa2Cu3O7 superconducting films were obtained on 36-mm-diam (100) LaAlO3 substrates with a lens rotating radius of 9 mm. The Tc's of the film center and edge were all 92 K and transition widths were less than 1 K. X-ray diffraction studies showed complete c-axis orientation of the films. The critical current density of 3.6×106 A/cm2 in zero field was measured at 77 K. A power law of voltage V versus current I of the YBa2Cu3O7 superconducting microbridge, V=1.363×10−32I11.224 49 was achieved.

    Nutrient-based Corn and Soy Products by Twin-screw Extrusion (1998)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Blends were developed to provide 20% protein, 12% fat, 68% carbohydrate and 8% moisture. High protein soy products (full fat flakes, protein isolate and/or concentrate) were formulated with corn meal and soybean oil to provide high protein and fat. The blends were extruded to provide pre-cooked foods that could be reconstituted at 40°C to a porridge or gruel, eliminating prolonged cooking or degradation of heat labile nutrients. Two types of soy isolate and concentrate were evaluated under extrusion temperatures from 100 to 130°C and feed moistures 8.5 to 18%. The extrusion of lower valued concentrates at 100 to 115°C with moisture from 12 to 18% produced a precooked mix that was high in nutrients and contained the most available lysine.
