51. Adiabatic Domain Wall Motion and Landau-Lifshitz Damping
Topic: Nanomagnetics
Published: 1/1/2007
Authors: Mark D Stiles, Wayne M. Saslow, Michael J Donahue, A Zangwill
Abstract: Recent theory and measurements of the velocity of current-driven domain walls in magnetic nanowires have re-opened the unresolved question of whether Landau-Lifshitz damping or Gilbert damping provides the more natural description of dissipative mag ...

52. Identification of the dominant precession damping mechanism in Fe, Co, and Ni by first-principles calculations
Topic: Nanomagnetics
Published: 1/1/2007
Authors: Keith Gilmore, Y Idzerda, Mark D Stiles
Abstract: The Landau-Lifshitz equation reliably describes magnetization dynamics using a phenomenological treatment of damping. This paper presents first-principles calculations of the damping parameters for Fe, Co, and Ni that quantitatively agree with exist ...

53. Implementation of a Non-Equilibrium Green's Function Method to Calculate Spin Transfer Torque
Topic: Nanomagnetics
Published: 1/1/2007
Authors: Christian Heiliger, M Czerner, B Yavorsky, I Mertig, Mark D Stiles
Abstract: We present an implementation of the steady state Keldysh approach in a Green function multiple scattering scheme to calculate the non-equilibrium spin density. This density is used to obtain the spin transfer torque in junctions showing the magneto r ...

54. SEMPA Imaging for Spintronics Applications
Topic: Nanomagnetics
Published: 1/1/2007
Authors: John Unguris, Daniel Thornton Pierce, Seok-Hwan Chung
Abstract: Scanning Electron Microscopy with Polarization Analysis (SEMPA) provides high resolution (10 nm) magnetization images simultaneously with, but independent of, the topography. Such information is very useful in studying spintronics devices as illustr ...

55. Spin-Orbit Precession Damping in Transition Metal Ferromagnets
Topic: Nanomagnetics
Published: 1/1/2007
Authors: Keith Gilmore, Y Idzerda, Mark D Stiles
Abstract: We provide a simple explanation, based on an effective field, for the precession damping rate due to the spin-orbit interaction. Previous effective field treatments of spin-orbit damping include only variations of the state energies with respect to ...

56. Tunneling Magnetoresistance With Amorphous Electrodes
Topic: Nanomagnetics
Published: 1/1/2007
Authors: M Gradhand, Christian Heiliger, P Zahn, I Mertig
Abstract: A detailed first principles analysis of the transport properties of different magnetic electrode materials for MgO tunnel junctions is performed to elucidate the microscopic origin of the TMR effect. The spin-dependent transport properties of the mag ...

57. Two Simple Tests for Models of Current-Induced Magnetization Switching
Topic: Nanomagnetics
Published: 1/1/2007
Authors: N Theodoropoulou, A Sharma, W Pratt, Mark D Stiles, J Xiao, J Bass
Abstract: We describe two simple tests for models of current-induced magnetization switching due to spin-transfer-torque in ferromagnetic/non-magnetic/ferromagnetic (F/N/F) trilayers. The first involves comparing calculated and measured values of the ratio X = ...

58. Magnetic Properties of Co/GaAs(110)
Topic: Nanomagnetics
Published: 12/4/2006
Authors: T Monchesky, John Unguris
Abstract: We observed three magnetic states of an ultrathin, atomically well-ordered Co film grown on a cleaved GaAs(110) substrate. For a Co thickness less than 3.4 monolayers (ML), we find a ferromagnetically dead layer associated with the formation of int ...

59. Spin Transfer Torque and Dynamics
Topic: Nanomagnetics
Published: 11/1/2006
Authors: Mark D Stiles, J Miltat
Abstract: The currents in magnetic multilayers are spin polarized and carry enough angular momentum that they can cause magnetic reversal and induce stable precession of the magnetization in thin magnetic layers. The flow of spins is determined by the spin{ma ...

60. Anisotropy of Magnetization Reversal and Magnetoresistance in Square Arrays of Permalloy Nano-Rings
Topic: Nanomagnetics
Published: 10/1/2006
Authors: A Goncharov, A Zhukov, V Metlushko, G Bordignon, H Fangohr, C de Groot, John Unguris, Willard C Uhlig, G Karapetrov, B Ilic, P A. de Groot
Abstract: Magnetization reversal mechanisms and the impact of magnetization direction are studied in square arrays of interconnected circular permalloy nanorings using magnetooptical Kerr effect, local imaging, numerical simulations, and transport techniques. ...
