Role of Magnon-Magnon Scattering in Magnon Polaron Spin Seebeck Effect
Zhong Shi, Qing Xi, Junxue Li +6
The spin Seebeck effect (SSE) signal of magnon polarons in bulk-Y3Fe5O12 (YIG)/Pt heterostructures is found to drastically change as a function of temperature. It appears as a dip…
Current-induced CrI3 surface spin-flop transition probed by proximity magnetoresistance in Pt
Tang Su, Mark Lohmann, Junxue Li +9
By exploiting proximity coupling, we probe the spin state of the surface layers of CrI3, a van der Waals magnetic semiconductor, by measuring the induced magnetoresistance (MR) of…
Coexistence of Magnetic Orders in Two-Dimensional Magnet CrI
Ben Niu, Tang Su, Brian A. Francisco +12
The magnetic properties in two-dimensional van der Waals materials depend sensitively on structure. CrI3, as an example, has been recently demonstrated to exhibit distinct magnetic…
Systematic Control of Strain-Induced Perpendicular Magnetic Anisotropy in Epitaxial Europium and Terbium Iron Garnets Thin Films
Victor H. Ortiz, Mohammed Aldosary, Junxue Li +6
We show tunable strain-induced perpendicular magnetic anisotropy (PMA) over a wide range of thicknesses in epitaxial ferrimagnetic insulator Eu3Fe5O12 (EuIG) and Tb3Fe5O12 (TbIG) t…
Effect of distance on photoluminescence quenching and proximity-induced spin-orbit coupling in graphene-WSe2 heterostructures
Bowen Yang, Everardo Molina, Jeongwoo Kim +9
Spin-orbit coupling (SOC) in graphene can be greatly enhanced by proximity coupling it to transition metal dichalcogenides (TMDs) such as WSe2. We find that the strength of the acq…
Dirac-Surface-State Modulated Spin Dynamics in a Ferrimagnetic Insulator at Room Temperature
Chi Tang, Qi Song, Cui-Zu Chang +10
This work demonstrates dramatically modified spin dynamics of magnetic insulator (MI) by the spin-momentum locked Dirac surface states of the adjacent topological insulator (TI) wh…
Direct observation of magnon-phonon coupling in yttrium iron garnet
Haoran Man, Zhong Shi, Guangyong Xu +7
The magnetic insulator yttrium iron garnet (YIG) with a ferrimagnetic transition temperature of 560 K has been widely used in microwave and spintronic devices. Anomalous feat…
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…
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…
Heat-driven spin transport in a ferromagnetic metal
Yadong Xu, Bowen Yang, Chi Tang +4
As a non-magnetic heavy metal is attached to a ferromagnet, a vertically flowing heat-driven spin current is converted to a transverse electric voltage, which is known as the longi…
