Furthermore\, the interfaces of complex o xides have been shown to exhibit unexpected functional properties not foun d in the constituent materials. These functional properties arise due to v arious structural and chemical changes as well as electronic and/or magnet ic interactions occurring over nanometer length scales at interfaces\, and they have the potential to be harnessed to enable new\, more versatile\, and energy efficient devices. In this talk\, I will present some of our re cent work investigating the interfacial interactions which occur at ferrom agnetic/antiferromagnetic (FM/AF) and FM/FM interfaces. While these interf acial interactions have been widely studied in metallic systems\, fundamen tal differences are observed in complex oxides systems. In this talk\, I w ill report on a unique spin-flop coupling observed at FM La0.7Sr0.3MnO3 /A FM La0.7Sr0.3FeO3 interfaces and contrast these interfaces to FM/FM interf aces consisting of hard FM La0.7Sr0.3CoO3 and soft FM La0.7Sr0.3MnO3 where exchange-spring behavior has been observed. These studies involved detail ed structural and magnetic characterization of the individual layers using a combination of resonant x-ray reflectometry and element-specific soft x -ray magnetic spectroscopy\, which provide key insight into interfacial ef fects over conventional characterization techniques such as bulk magnetome try. These results demonstrate how the many competing interactions in comp lex oxide heterostructures opens up new intriguing opportunities to tailor their functional properties for future spintronic device applications.\n\ nCo-sponsored by: UCCS\n\nSpeaker(s): Yayoi Takamura\, \n\nRoom: A204\, Bl dg: Osborne\, 1420 Austin Bluffs Park\, Colorado Springs\, Colorado\, Unit ed States\, 80918 LOCATION:Room: A204\, Bldg: Osborne\, 1420 Austin Bluffs Park\, Colorado Sp rings\, Colorado\, United States\, 80918 ORGANIZER:zcelinsk@uccs.edu SEQUENCE:0 SUMMARY:Engineering Magnetic Interactions in Complex Oxide Heterostructures URL;VALUE=URI:https://events.vtools.ieee.org/m/216654 X-ALT-DESC:Description: <br /><p>Complex oxides possess a wide range of int riguing and technologically relevant functional properties including ferro magnetism\, ferroelectricity\, and superconductivity.
