31. 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 ...

32. 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 ...

33. 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 ...

36. 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 ...

37. 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 ...

38. Direct Observation of Spin Configurations and Classification of Switching Processes in Mesoscopic Ferromagnetic Rings
Topic: Nanomagnetics
Published: 10/1/2003
Authors: M Klaui, C Vaz, J Bland, T Monchesky, John Unguris, G r SPELEEM, L J Heyderman, Z Cui
Abstract: Using non-intrusive imaging techniques we have directly observed the nanoscopic details of the magnetization configurations of epitaxial and polycrystalline mesoscopic ring structures with <15 nm resolution. We have found head to head domain walls w ...

39. Domain Images of Ultrathin Fe Films on Ag(100)
Topic: Nanomagnetics
Published: 5/30/1988
Authors: J L Robins, Robert Celotta, John Unguris, Daniel Thornton Pierce, B Jonker, G Prinz
Abstract: Scanning electron microscopy with electron polarization analysis has been used to image domains of ultrathin Fe films grown epitaxially on a Ag(100) substrate. Room-temperature measurements show clearly the existence of large domains of in-plane magn ...

40. Domain Structures in Magnetoresistive Granular Metals
Topic: Nanomagnetics
Published: 1/1/1995
Authors: A Gavrin, Michael H Kelley, J Xiao, C Chien, Robert Celotta
Abstract: We have imaged the magnetic domain structure of several heterogeneous Co^dx^Ag^d1-x^ alloys by using scanning electron microscopy with polarization analysis. These images show that extended domain structures exist in both the as-deposited samples and ...
