Strain-Tunable Magnetocrystalline Anisotropy in Epitaxial Y3Fe5O12 Thin Films
Hailong Wang, Chunhui Du, Chris Hammel +1
We demonstrate strain-tuning of magnetocrystalline anisotropy over a range of more than one thousand Gauss in epitaxial Y3Fe5O12 films of excellent crystalline quality grown on lat…
Probing the Spin Pumping Mechanism: Exchange Coupling with Exponential Decay in Y3Fe5O12/barrier/Pt Heterostructures
C. H. Du, H. L. Wang, Y. Pu +4
Ferromagnetic resonance driven spin pumping of pure spin currents from a ferromagnet into a nonmagnetic material promises new spin-functional devices with low energy consumption. T…
Large Spin Pumping from Epitaxial Y3Fe5O12 Thin Films to Pt and W Layers
H. L. Wang, C. H. Du, Y. Pu +3
Epitaxial Y3Fe5O12 thin films have been deposited by off-axis sputtering, which exhibit excellent crystalline quality, enabling observation of large spin pumping signals in Pt/Y3Fe…
Scaling of spin Hall angle in 3d, 4d and 5d metals from Y3Fe5O12/metal spin pumping
H. L. Wang, C. H. Du, Y. Pu +3
Pure spin currents generated by spin pumping in ferromagnet/nonmagnet (FM/NM) bilayers produce inverse spin Hall effect (ISHE) voltages in the NM, from which spin pumping and trans…
Long-range FMR driven spin pumping through a nonmagnetic insulator
Y. Pu, H. L. Wang, C. H. Du +8
Ferromagnetic resonance (FMR) driven spin pumping is an emerging technique for injection of a pure spin current from a ferromagnet (FM) into a non-magnetic (NM) material without an…
