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…
First and second order magnetic anisotropy and damping of europium iron garnet under high strain
Victor H. Ortiz, Bassim Arkook, Junxue Li +8
Understanding and tailoring static and dynamic properties of magnetic insulator thin films is important for spintronic device applications. Here, we grow atomically flat epitaxial…
Ultrafast Measurements of the Interfacial Spin Seebeck Effect in Au and Rare-Earth Iron Garnet Bilayers
Victor H. Ortiz, Michael J. Gomez, Yawen Liu +3
We investigate picosecond spin-currents across Au/iron-garnet interfaces in response to ultrafast laser heating of the electrons in the Au film. In the picoseconds after optical he…
Mapping the intrinsic photocurrent streamlines through micromagnetic heterostructure devices
Morgan Mayes, Farima Farahmand, Maxwell Grossnickle +7
Like air flowing over a wing, optimizing the flow of electronic charge is essential to the operation of nanoscale devices. Unfortunately, the delicate interplay of charge, spin, an…
Spin Seebeck effect from antiferromagnetic magnons and critical spin fluctuations in epitaxial FeF2 films
Junxue Li, Zhong Shi, Victor H. Ortiz +5
We report a longitudinal spin Seebeck effect (SSE) study in epitaxially grown FeF2(110) antiferromagnetic (AFM) thin films with strong uniaxial anisotropy over the temperature rang…
Highly efficient spin-orbit torque and switching of layered ferromagnet Fe3GeTe2
Mohammed Alghamdi, Mark Lohmann, Junxue Li +6
Among van der Waals (vdW) layered ferromagnets, Fe3GeTe2 (FGT) is an excellent candidate material to form FGT/heavy metal heterostructures for studying the effect of spin-orbit tor…
Probing Magnetism in Insulating Cr2Ge2Te6 by Induced Anomalous Hall Effect in Pt
Mark Lohmann, Tang Su, Ben Niu +10
Two-dimensional ferromagnet Cr2Ge2Te6 (CGT) is so resistive below its Curie temperature that probing its magnetism by electrical transport becomes extremely difficult. By forming h…
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…
Exploring interfacial exchange coupling and sublattice effect in heavy metal/ferrimagnetic insulator heterostructures using Hall measurements, x-ray magnetic circular dichroism, and neutron reflectometry
Qiming Shao, Alexander Grutter, Yawen Liu +13
We use temperature-dependent Hall measurements to identify contributions of spin Hall, magnetic proximity, and sublattice effects to the anomalous Hall signal in heavy metal/ferrim…
Approaching quantum anomalous Hall effect in proximity-coupled YIG/graphene/h-BN sandwich structure
Chi Tang, Bin Cheng, Mohammed Aldosary +6
Quantum anomalous Hall state is expected to emerge in Dirac electron systems such as graphene under both sufficiently strong exchange and spin-orbit interactions. In pristine graph…
Deficiency of the Bulk Spin Hall Effect Model for Spin-Orbit Torques in Magnetic Insulator/Heavy Metal Heterostructures
Junxue Li, Guoqiang Yu, Chi Tang +9
Electrical currents in a magnetic insulator/heavy metal heterostructure can induce two simultaneous effects, namely, spin Hall magnetoresistance (SMR) on the heavy metal side and s…
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…
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…
