21. Chirality from interfacial spin-orbit coupling effects in magnetic bilayers
Topic: Nanomagnetics
Published: 11/19/2013
Authors: Kyoung-Whan Kim, Hyun-Woo Lee, Kyung Jin Lee, Mark D Stiles
Abstract: Spin-orbit coupling causes many properties that make magnets technologically important as well as properties that interfere with optimal performance. As nanomagnetic devices scale to smaller sizes, spin-orbit coupling due to the broken structural inv ...

22. Coercivities above 10 kOe in CoPd Superlattices
Topic: Nanomagnetics
Published: 1/1/2004
Authors: William F. Egelhoff Jr., Cedric John Powell, L Gan, P J Chen, H Ettendgui, D Tirosh, Robert D McMichael, Mark D Stiles, J Mallett, Alexander J. Shapiro, John E Bonevich
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 ...

23. Coercivity in Exchange-Bias Bilayers
Topic: Nanomagnetics
Published: 1/18/2001
Authors: Mark D Stiles, Robert D McMichael
Abstract: Simulations of magnetic reversal in polycrystalline exchange-bias bilayers exhibit two contributions to the enhanced coercivity found in exchange-bias systems, one due to inhomogeneous reversal and and the other to irreversible transitions in the ant ...

24. Coercivity of Ultrathin Films with In-plane Magnetization
Topic: Nanomagnetics
Published: 4/15/1997
Authors: R Hyman, Mark D Stiles, L Tang, A Zangwill
Abstract: We report numerical and analytic results for a model of coercivity and magnetization reversal in an array of square monolayer-height magnetic islands on a monolayer of magnetic material with in-plane magnetization. Reversal nucleates at step edges w ...

25. Comment on Exchange Coupling in Magnetic Multilayers: A Quantum-Size Effect
Topic: Nanomagnetics
Published: 1/1/1995
Authors: P Bruno, Mark D Stiles, Y Yafet

26. Connection Between Surface Magnetism and Electronic Structure of Oxygen on Ni(110)
Topic: Nanomagnetics
Published: 1/1/1985
Authors: A Seiler, C Feigerle, J Pena, Robert Celotta, Daniel Thornton Pierce
Abstract: The d-band holes which give rise to ferromagnetism in Ni can be directly observed by spin-polarized inverse photoelectron spectroscopy (SPIPES). Only incident electrons polarized in the minority spin direction can fall into unfilled minority spin sta ...

27. Control of magnetic fluctuations by spin current
Topic: Nanomagnetics
Published: 9/2/2011
Authors: Vladislav E Demidov, Sergei Urazhdin, Eric Edwards, Mark D Stiles, Robert D McMichael, Sergej O Demokritov
Abstract: We utilize micro-focus Brillouin light scattering spectroscopy to study the interaction of spin current generated by the spin Hall effect with magnetic fluctuations in a Permalloy microdisc. We show that the fluctuations can be efficiently enhanced o ...

28. Correlations Between Magnetic Microstructure and Anisotropy with Noise Spectra for CoNi and CoCrTa Thin Film Media
Topic: Nanomagnetics
Published: 1/1/1990
Authors: M Scheinfein, John Unguris, Daniel Thornton Pierce, Robert Celotta
Abstract: This paper reports on two thin film media alloys co^d86^Cr^d12^Ta^d2^ and Co^d75^Ni^d25^ whcih have very different noise characteristics. The magnetic microstructure of thse films was observed with SEMPA. The anisotropy and teh rotational hysteresi ...

29. Correlations of Modulation Noise with Magnetic Microstructure and Intergranular Interactions for CoCrTa and CoNi Thin Film Media
Topic: Nanomagnetics
Published: 1/1/1991
Authors: Mahbub R. Khan, S Y. Lee, S L Duan, J L Pressesky, Neil Heiman, D E Speliotis, M Scheinfein
Abstract: This paper reports on two thin-film media alloys Co^d86^Cr^d12^Ta^d2^ and Co^d75^Ni^d25^ which have very different noise characteristics. The magnetic microstructure of these films was observed with scanning electron microscopy with polarization anal ...

30. Critical behavior of zero-field magnetic fluctuations in perpendicularly magnetized thin films
Topic: Nanomagnetics
Published: 11/4/2014
Authors: Andrew Lee Balk, Mark D Stiles, John Unguris
Abstract: We use video-rate magneto optical Kerr effect (MOKE) microscopy to study zero field magnetic fluctuations in a perpendicularly magnetized cobalt film at room temperature, prepared near a spin reorientation transition. Globally, the film has zero net ...
