This presentation will discuss layered struct ures where a topological insulator interfaces with a magnetic insulator. T his system is of particular interest for three main reasons: (1) one can u se a magnetic insulator to pump spins into a topological insulator\; by me asuring the resultant responses in the topological insulator\, one can rev eal the nature of the topological surface states\; (2) the system allows u s to explore how to take advantage of the topological surface states to ma nipulate magnetism\; (3) it enables the realization of new quantum states. \n\nThis presentation consists of three parts. Part I will discuss experim ents on spin pumping from a magnetic insulator Y3Fe5O12 slab to a topologi cal Kondo insulator SmB6 thin film\; the experiments advanced the understa nding of the topological surface states in SmB6. Parts II and III will rep ort on how to use the topological surface states in a topological insulato r to manipulate magnetism in a neighboring magnetic insulator. Part II wil l discuss how the topological surface states in a topological insulator Bi 2Se3 thin film modify the magnetic ordering in a neighboring Y3Fe5O12 thin film\, while Part III will be on the use of the topological surface state s in a Bi2Se3 thin film to induce magnetization switching in a neighboring a magnetic insulator BaFe12O19 thin film.\n\nCo-sponsored by: UCCS\n\nSpe aker(s): Mingzhong Wu\, \n\nRoom: A204\, Bldg: Osborne\, 1420 Austin Bluff s 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:Topological Insulator/Magnetic Insulator Heterostructures URL;VALUE=URI:https://events.vtools.ieee.org/m/216617 X-ALT-DESC:Description: <br /><p style="text-align: justify\;">Recent years have witnessed a rapidly growing interest in topological insulators\, not only because of rich intriguing physics in such materials\, but also due to their promising potential in quantum computing and spintronics applicat ions.&nbsp\; This presentation will discuss layered structures where a top ological insulator interfaces with a magnetic insulator.&nbsp\; This syste m is of particular interest for three main reasons: (1) one can use a magn etic insulator to pump spins into a topological insulator\; by measuring t he resultant responses in the topological insulator\, one can reveal the n ature of the topological surface states\; (2) the system allows us to expl ore how to take advantage of the topological surface states to manipulate magnetism\; (3) it enables the realization of new quantum states.&nbsp\;</ p>\n<p style="text-align: justify\;">This presentation consists of three p arts.&nbsp\; Part I will discuss experiments on spin pumping from a magnet ic insulator Y<sub>3</sub>Fe<sub>5</sub>O<sub>12</sub> slab to a topologic al Kondo insulator SmB<sub>6</sub> thin film\; the experiments advanced th e understanding of the topological surface states in SmB<sub>6</sub>.&nbsp \; Parts II and III will report on how to use the topological surface stat es in a topological insulator to manipulate magnetism in a neighboring mag netic insulator.&nbsp\; Part II will discuss how the topological surface s tates in a topological insulator Bi<sub>2</sub>Se<sub>3</sub> thin film mo dify the magnetic ordering in a neighboring Y<sub>3</sub>Fe<sub>5</sub>O<s ub>12</sub> thin film\, while Part III will be on the use of the topologic al surface states in a Bi<sub>2</sub>Se<sub>3</sub> thin film to induce ma gnetization switching in a neighboring a magnetic insulator BaFe<sub>12</s ub>O<sub>19</sub> thin film.</p> END:VEVENT END:VCALENDAR
