Alle viating this rise in power consumption requires rethinking the way we elec tronically process and store information. Spintronics\, or spin electronic s\, offers a possible solution to this problem by using spin currents or s pin waves rather than conventional charge currents to manipulate informati on. A key ingredient in spintronics is spin-orbit coupling: the relativist ic coupling between a particle’s spin and orbital moments. Spin-orbit co upling permits conduction electrons to extract a virtually unlimited amoun t of angular momentum from the crystal lattice\, potentially enabling ener gy efficient information processing. In this talk\, I will discuss the ele ctrical manipulation of a ferromagnet’s magnetization through spin-orbit coupling. This phenomenon\, known as spin-orbit torque\, could help harne ss all the advantages of different electronic memories (e.g. speed\, nonvo latility\, radiation hardness) into one device. The present understanding of spin-orbit torque is incomplete because there is no consensus among the ory and experiment over the important mechanisms. We review the traditiona l spin-orbit torque mechanisms and then show that novel interfacial or bul k effects are needed to explain recent experiments. Shedding light on thes e mechanisms will help clarify the nature of spin-orbit torque\, creating exciting new possibilities for current-controlled magnetization dynamics w ith attractive applications for information processing.\n\nCo-sponsored by : UCCS\n\nSpeaker(s): Vivek Amin\, \n\nRoom: A204\, Bldg: Osborne\, 1420 A ustin Bluffs Pkwy\, Colorado Springs\, Colorado\, United States\, 80918 LOCATION:Room: A204\, Bldg: Osborne\, 1420 Austin Bluffs Pkwy\, Colorado Sp rings\, Colorado\, United States\, 80918 ORGANIZER:zcelinsk@uccs.edu SEQUENCE:0 SUMMARY:Anatomy of spin-orbit torque URL;VALUE=URI:https://events.vtools.ieee.org/m/216602 X-ALT-DESC:Description: <br /><p><span style="font-size: 14.0pt\; font-fami ly: 'Calibri Light'\,sans-serif\;">Information and communications technolo gy is predicted to account for 10% to 20% of the world&rsquo\;s power cons umption within a decade.&nbsp\; Alleviating this rise in power consumption requires rethinking the way we electronically process and store informati on.&nbsp\; Spintronics\, or spin electronics\, offers a possible solution to this problem by using spin currents or spin waves rather than conventio nal charge currents to manipulate information.&nbsp\; A key ingredient in spintronics is spin-orbit coupling: the relativistic coupling between a pa rticle&rsquo\;s spin and orbital moments.&nbsp\; Spin-orbit coupling permi ts conduction electrons to extract a virtually unlimited amount of angular momentum from the crystal lattice\, potentially enabling energy efficient information processing.&nbsp\; In this talk\, I will discuss the electric al manipulation of a ferromagnet&rsquo\;s magnetization through spin-orbit coupling.&nbsp\; This phenomenon\, known as spin-orbit torque\, could hel p harness all the advantages of different electronic memories (e.g. speed\ , nonvolatility\, radiation hardness) into one device.&nbsp\; The present understanding of spin-orbit torque is incomplete because there is no conse nsus among theory and experiment over the important mechanisms.&nbsp\; We review the traditional spin-orbit torque mechanisms and then show that nov el interfacial or bulk effects are needed to explain recent experiments.&n bsp\; Shedding light on these mechanisms will help clarify the nature of s pin-orbit torque\, creating exciting new possibilities for current-control led magnetization dynamics with attractive applications for information pr ocessing.</span></p>\n<p>&nbsp\;</p> END:VEVENT END:VCALENDAR
