Two Strategies to Measure Spin-Orbit-Torque Efficiency Acting on the Insulating Magnet LiAlFeO
Orion Smedley, Thow Min Jerald Cham, Daisy O'Mahoney +10
For insulating magnets, widely-used electrically-based techniques to measure spin-orbit-torque efficiency can suffer from poor signal-to-noise ratios and unwanted artifacts, while…
Imaging Harmonic Generation of Magnons
Anthony J. D'Addario, Kwangyul Hu, Maciej W. Olszewski +4
This work combines theory and experiment to examine the mechanisms underlying the harmonic generation of magnons. We develop a nonlinear spin-wave framework that is directly analog…
Anisotropic spin-orbit torque generation in epitaxial SrIrO3 by symmetry design
T. Nan, T. J. Anderson, J. Gibbons +13
Spin-orbit coupling (SOC), the interaction between the electron spin and the orbital angular momentum, can unlock rich phenomena at interfaces, in particular interconverting spin a…
Efficient Switching of 3-Terminal Magnetic Tunnel Junctions by the Giant Spin Hall Effect of Alloy
Minh-Hai Nguyen, Shengjie Shi, Graham E. Rowlands +4
Recent research has indicated that introducing impurities that increase the resistivity of Pt can enhance the efficiency of the spin Hall torque it generates. Here we directly demo…
Fast, low-current spin-orbit torque switching of magnetic tunnel junctions through atomic modifications of the free layer interfaces
Shengjie Shi, Yongxi Ou, S. V. Aradhya +2
Future applications of spin-orbit torque will require new mechanisms to improve the efficiency for switching nanoscale magnetic tunnel junctions (MTJs), while also controlling the…
Strong perpendicular magnetic anisotropy energy density at Fe alloy/HfO2 interfaces
Yongxi Ou, D. C. Ralph, R. A. Buhrman
We report on the perpendicular magnetic anisotropy (PMA) behavior of heavy metal (HM)/ Fe alloy/MgO thin film heterostructures after an ultrathin HfO2 passivation layer is inserted…
