Liu T, Kally J, Pillsbury T, Liu C, Chang H, Ding J, et al.
Phys Rev Lett . 2020 Jul; 125(1):017204. PMID: 32678653
We report the modification of magnetism in a magnetic insulator Y_{3}Fe_{5}O_{12} thin film by topological surface states (TSS) in an adjacent topological insulator Bi_{2}Se_{3} thin film. Ferromagnetic resonance measurements show...

Liu T, Li Y, Gu L, Ding J, Chang H, Janantha P, et al.
Phys Rev Lett . 2018 Jun; 120(20):207206. PMID: 29864320
The nontrivial feature and penetration depth of the topological surface states (TSS) in SmB_{6} were studied via spin pumping. The experiments used SmB_{6} thin films grown on the bulk magnetic...

Liu C, Chen J, Liu T, Heimbach F, Yu H, Xiao Y, et al.
Nat Commun . 2018 Feb; 9(1):738. PMID: 29467416
Recent years have witnessed a rapidly growing interest in exploring the use of spin waves for information transmission and computation toward establishing a spin-wave-based technology that is not only significantly...

Chang H, Janantha P, Ding J, Liu T, Cline K, Gelfand J, et al.
Sci Adv . 2017 Apr; 3(4):e1601614. PMID: 28435873
The role of damping in the spin Seebeck effect (SSE) was studied experimentally for the first time. The experiments used YFeO (YIG)/Pt bilayered structures where the YIG films exhibit very...

Li P, Liu T, Chang H, Kalitsov A, Zhang W, Csaba G, et al.
Nat Commun . 2016 Sep; 7:12688. PMID: 27581060
As an in-plane charge current flows in a heavy metal film with spin-orbit coupling, it produces a torque on and thereby switches the magnetization in a neighbouring ferromagnetic metal film....

Wang H, Kally J, Lee J, Liu T, Chang H, Reifsnyder Hickey D, et al.
Phys Rev Lett . 2016 Aug; 117(7):076601. PMID: 27563980
We report the observation of ferromagnetic resonance-driven spin pumping signals at room temperature in three-dimensional topological insulator thin films-Bi_{2}Se_{3} and (Bi,Sb)_{2}Te_{3}-deposited by molecular beam epitaxy on Y_{3}Fe_{5}O_{12} thin films. By...

Sun Y, Chang H, Kabatek M, Song Y, Wang Z, Jantz M, et al.
Phys Rev Lett . 2014 Aug; 111(10):106601. PMID: 25166689
Strong damping enhancement in nm-thick yttrium iron garnet (YIG) films due to Pt capping layers was observed. This damping is substantially larger than the expected damping due to conventional spin...
