Magnon-mediated spin currents in Tm3Fe5O12/Pt with perpendicular magnetic anisotropy
G. L. S. Vilela, J. E. Abrao, E. Santos +7
The control of pure spin currents carried by magnons in magnetic insulator (MI) garnet films with a robust perpendicular magnetic anisotropy (PMA) is of great interest to spintroni…
Hypergiant spin polarons photogenerated in ferromagnetic europium chalcogenides
X. Gratens, Yunbo Ou, J. Moodera +2
We find that in the ferromagnetic semiconductor EuS, near its Curie temperature, a single band-edge photon generates a spin polaron (SP), whose magnetic moment approaches 20,000 Bo…
Strain-Tuned Magnetic Anisotropy in Sputtered Thulium Iron Garnet Ultrathin Films and TIG/Au/TIG Valve Structures
Gilvânia Vilela, Hang Chi, Gregory Stephen +6
Defining the magnetic anisotropy for in-plane or out-of-plane easy axis in ferrimagnetic insulators films by controlling the strain, while maintaining high-quality surfaces, is des…
Large Enhancement of Critical Current in Superconducting Devices by Gate Voltage
Mirko Rocci, Dhavala Suri, Akashdeep Kamra +5
The gate-voltage-induced suppression of critical currents in metallic superconductors observed recently [De Simoni et al., Nat. Nanotechnol. 13, 802 (2018)] has raised crucial ques…
