31. Current induced torques and interfacial spin-orbit coupling: semiclassical modeling
Topic: Nanomagnetics
Published: 5/7/2013
Authors: Paul M Haney, Hyun-Woo Lee, Kyung Jin Lee, Aurelien Manchon, Mark D Stiles
Abstract: Currents passing through bilayer nanowires with a ferromagnetic layer and a non-magnetic layer with strong spin-orbit coupling, excite magnetic dynamics which cannot be explained with standard models. The dynamics appear to require two torques which ...

32. Current-Induced Spin-Wave Excitations in a Single Ferromagnetic Layer
Topic: Nanomagnetics
Published: 3/14/2003
Authors: Yi Ji, C Chien, Mark D Stiles
Abstract: Evidence for a current induced spin-transfer torque effect has been investigated in a series of point contacts to single ferromagnetic layers. At specific current densities, abrupt resistance changes, similar to those attributed to current-induced s ...

33. Current-driven switching in a single exchange-biased ferromagnetic layer
Topic: Nanomagnetics
Published: 7/9/2004
Authors: Tingyong Chen, Yi Ji, C Chien, Mark D Stiles
Abstract: We demonstrate spin-transfer torque effects in a single exchange-biased ferromagnetic layer. A current through a point contact to the exchange-biased Co layer reverses the magnetization of a nanodomain in the layer hysteretically for low applied magn ...

34. Current-induced switching in a single exchange-biased ferromagnetic layer
Topic: Nanomagnetics
Published: 5/15/2005
Authors: Tingyong Chen, Yi Ji, C Chien, Mark D Stiles
Abstract: We demonstrate current-induced switching effects in a single exchanged-biased ferromagnetic layer. A nanodomain can be switched within the ferromagnetic layer by a spin polarized current injected through a point contact. The high resistance of the hy ...

35. Damping phenomena in Co^d90^Fe^d10^/Ni multilayers and alloys
Topic: Nanomagnetics
Published: 7/6/2011
Authors: Justin M Shaw, Hans T. Nembach, Thomas J Silva
Abstract: We used perpendicular ferromagnetic resonance to measure the damping parameter in Co^d90^Fe^d10^/Ni multilayers over a wide range of layer thicknesses. The magnetic anisotropy within this range varied from in-pane to out-of-plane. We measured (Co^d90 ...

36. Definition of Ultimate Attainable Spatial Resolution
Topic: Nanomagnetics
Published: 1/1/1989
Author: M Scheinfein

37. Determination of spin pumping as a source of linewidth sputtered Co^d90^Fe^d10^/Pd multilayers by use of broadband ferromagnetic resonance spectroscopy
Topic: Nanomagnetics
Published: 2/10/2012
Authors: Justin M Shaw, Hans T. Nembach, Thomas J Silva
Abstract: We performed a systematic study of damping in Co^d90^Fe^d10^/Pd multilayers by use of broadband (1‹ 60 GHz) ferromagnetic resonance (FMR) spectroscopy in the perpendicular geometry. The data were fitted with the conventional Landau-Lifshitz equation ...

38. Determination of the Exchange Coupling Strengths for Fe/Au/Fe
Topic: Nanomagnetics
Published: 10/6/1997
Authors: John Unguris, Robert Celotta, Daniel Thornton Pierce

39. Direct Imaging of Current Driven Domain Walls in Ferromagnetic Nanostripes
Topic: Nanomagnetics
Published: 5/21/2009
Authors: Willard C Uhlig, Michael J Donahue, Daniel Thornton Pierce, John Unguris
Abstract: To better understand the response of domain walls to current induced spin transfer torques, we have directly imaged the internal magnetic structure of domain walls in current-carrying ferromagnetic nanostripes. Domain wall images were acquired both ...

40. Direct Observation of Remanent Magnetic States in Epitaxial fcc Co Small Disks
Topic: Nanomagnetics
Published: 4/1/2003
Authors: C Vaz, L Lopez-Diaz, M Klaui, J Bland, T Monchesky, John Unguris, Z Cui
Abstract: The magnetic nanostructure of epitaxial fcc Co/Cu(001) circular elements (~1.7{mu}m in diameter) has been imaged with scanning electron microscopy with polarization analysis. The disks are obtained by ultrahigh vacuum deposition of the metal films on ...
