61. Effect of Film Composition on the Orientation of (Ba,Sr)TiO^d3^ Grains in (Ba,Sr)^dy^TiO^d2+y^ Thin Films
Published: 1/12/1999
Authors: Debra L Kaiser, Mark D Vaudin, L D. Rotter, John E Bonevich, J T. Armstrong
Abstract: (Ba,Sr)^dy^TiO^d2+y^ thin films with 0.34 {< or =} y {< or =} 1.64 were deposited by metalorganic chemical vapor deposition (MOCVD) on (100) MgO substrates at various growth conditions. X-ray diffraction and transmission electron microscopy studies ...

62. The Growth Kinetics of Nanocrystalline ZnO Colloidal Solutions
Published: 9/11/1998
Authors: E M Wong, John E Bonevich, P C Searson
Abstract: Colloidal chemistry techniques were used to synthesize ZnO particles in the nanometer size regime. Although the synthesis and unique properties of these materials are well known, the kinetics of the growth process are not well understood. The parti ...

63. Stability of Multilayer Structures: Capillary Effects
Published: 6/1/1998
Authors: Daniel Josell, W Carter, John E Bonevich
Abstract: The long term stability of multilayer materials composed of nonreactive, immiscible materials is related to the equilibrium shapes of the individual grains within the layers. These shapes are determined by the free energies and locations of the inte ...

64. Coercivities Above 10 kOe in CoPd Superlattices
Published: Date unknown
Authors: William F. Egelhoff Jr., Cedric John Powell, L Gan, P J Chen, H Ettedgui, D Tirosh, Robert D McMichael, Mark D Stiles, J Mallett, Alexander J. Shapiro, John E Bonevich, J H Judy, Erik B. Svedberg, A. E. Berkowitz
Abstract: We have achieved excellent grain isolation in CoPd superlattices by using 10 nm Au as both an underlayer and an overlayer and diffusing Au into the grain boundaries by annealing for {approximately equal to} 30 min. at 300 degrees C. The grain isola ...

65. Suppressing of Unidirectional Coupling in Magnetic Tunnel Junctions by Preoxidation: Structural Studies
Published: Date unknown
Authors: William F. Egelhoff Jr., Robert D McMichael, Mark D Stiles, Cedric John Powell, John E Bonevich, M Wormington, D S Eastwood, B K Tanner
Abstract: Pre-oxidation of the bottom electrode prior to deposition of Al_{2}O_{3} or MgO is very effective as a general approach to suppressing the unidirectional coupling that is commonly observed in magnetic tunnel junctions. In this paper, we report struc ...

66. Surfactant Effect in the Suppressing of Orange-Peel Coupling in Magnetic Tunnel Junctions by Pre-Oxidation
Published: Date unknown
Authors: William F. Egelhoff Jr., Robert D McMichael, Mark D Stiles, Cedric John Powell, John E Bonevich, M Wormington
Abstract: Pre-oxidation of the bottom electrode prior to deposition of Al2O3 or MgO is very effective as a general approach to suppressing orange-peel coupling in magnetic tunnel junctions. In this paper, we report structural studies on this effect using grazi ...

67. Underpotential Co-Deposition of Cu_subscript(1-x)Pt_subscript(x) Alloys
Published: Date unknown
Authors: J Mallett, Ugo Bertocci, Erik B. Svedberg, John E Bonevich, Alexander J. Shapiro, William F. Egelhoff Jr., Thomas P Moffat
Abstract: The electrodeposition of Cu_subscript (1-x)Pt_subscript(x) alloys by underpotential co-deposition of Cu with Pt is demonstrated using an H_subscript(2)SO_subscript(4)-CuSO_subscript(4-)PtCl_subscript(4)_superscript(2-) electrolyte. The composition a ...
