Anomalous Hall hysteresis in Tm3Fe5O12/Pt with strain-induced perpendicular magnetic anisotropy
Chi Tang, Pathikumar Sellappan, Yawen Liu +3
We demonstrate robust interface strain-induced perpendicular magnetic anisotropy in atomically flat ferrimagnetic insulator Tm3Fe5O12 films grown with pulsed laser deposition on su…
An integrated approach to doped thin films with strain tunable magnetic anisotropy: Powder synthesis, target preparation and pulsed laser deposition of Bi:YIG
Pathikumar Sellappan, Chi Tang, Jing Shi +1
We present a synthesis/processing method for fabricating ferrimagnetic insulator (Bi-doped yttrium iron garnet) thin films with tunable magnetic anisotropy. Since the desired magne…
Platinum/Yttrium Iron Garnet Inverted Structures for Spin Current Transport
Mohammed Aldosary, Junxue Li, Chi Tang +4
30-80 nm thick yttrium iron garnet (YIG) films are grown by pulsed laser deposition on a 5 nm thick sputtered Pt atop gadolinium gallium garnet substrate (GGG) (110). Upon post-gro…
Enhanced spin Seebeck effect signal due to spin-momentum locked topological surface states
Zilong Jiang, Cui-Zu Chang, Massoud Ramezani Masir +5
Spin-momentum locking in protected surface states enables efficient electrical detection of magnon decay at a magnetic-insulator/topological-insulator heterojunction. Here we demon…
Observation of magnon-mediated current drag in Pt/yttrium iron garnet/Pt(Ta) trilayers
Junxue Li, Yadong Xu, Mohammed Aldosary +5
Pure spin current, a flow of spin angular momentum without flow of any companying net charge, is generated in two common ways. One makes use of the spin Hall effect in normal metal…
