Changes of Magnetism in a Magnetic Insulator due to Proximity to a Topological Insulator
Tao Liu, James Kally, Timothy Pillsbury +9
This letter reports the modification of magnetism in a magnetic insulator Y3Fe5O12 thin film by topological surface states (TSS) in an adjacent topological insulator Bi2Se3 thin fi…
Thermally driven two-magnet nano-oscillator with large spin-charge conversion
Bassim Arkook, Christopher Safranski, Rodolfo Rodriguez +8
Next-generation spintronic applications require material properties that can be hardly met by one material candidate. Here we demonstrate that by combining insulating and metallic…
First harmonic measurements of the spin Seebeck effect
Yizhang Chen, Debangsu Roy, Egecan Cogulu +3
We present measurements of the spin Seebeck effect (SSE) by a technique that combines alternating currents (AC) and direct currents (DC). The method is applied to a ferrimagnetic i…
Patterned growth of crystalline YFeO nanostructures with engineered magnetic shape anisotropy
Na Zhu, Houchen Chang, Andrew Franson +5
We demonstrate patterned growth of epitaxial yttrium iron garnet (YIG) thin films using lithographically defined templates on gadolinium gallium garnet (GGG) substrates. The fabric…
Spin caloritronic nano-oscillator
Chris Safranski, Igor Barsukov, Han Kyu Lee +9
Energy loss due to ohmic heating is a major bottleneck limiting down-scaling and speed of nano-electronic devices, and harvesting ohmic heat for signal processing is a major challe…
Spin transport in antiferromagnetic NiO and magnetoresistance in YFeO/NiO/Pt structures
Yu-Ming Hung, Christian Hahn, Houchen Chang +3
We have studied spin transport and magnetoresistance in yttrium iron garnet (YIG)/NiO/Pt trilayers with varied NiO thickness. To characterize the spin transport through NiO we exci…
Surface state dominated spin-charge current conversion in topological insulator/ferromagnetic insulator heterostructures
Hailong Wang, James Kally, Joon Sue Lee +7
We report the observation of ferromagnetic resonance-driven spin pumping signals at room temperature in three-dimensional topological insulator thin films -- Bi2Se3 and (Bi,Sb)2Te3…
Driving and detecting ferromagnetic resonance in insulators with the spin Hall effect
Joseph Sklenar, Wei Zhang, Matthias B. Jungfleisch +6
We demonstrate the generation and detection of spin-torque ferromagnetic resonance in Pt/YIG bilayers. A unique attribute of this system is that the spin Hall effect lies at the he…
Spin waves in micro-structured yttrium iron garnet nanometer-thick films
Matthias B. Jungfleisch, Wei Zhang, Wanjun Jiang +8
We investigated the spin-wave propagation in a micro-structured yttrium iron garnet waveguide of nm thickness. Utilizing spatially-resolved Brillouin light scattering microsco…
