First-principle study of spin transport property in -FePd(001)/graphene heterojunction
Hayato Adachi, Ryuusuke Endo, Hikari Shinya +3
In our previous work, we synthesized a metal/2D material heterointerface consisting of -ordered iron-palladium (FePd) and graphene (Gr) called FePd(001)/Gr. This system has b…
Density functional study of twisted graphene -FePd heterogeneous interface
Mitsuharu Uemoto, Hayato Adachi, Hiroshi Naganuma +1
Graphene on -FePd(001), which has been experimentally studied in recent years, is a heterogeneous interface with a significant lattice symmetry mismatch between the honeycomb…
Realization of a spin wave switch based on the Spin-Transfer-Torque effect
Thomas Meyer, Thomas Brächer, Frank Heussner +7
We investigate the amplification of externally excited spin waves via the Spin-Transfer-Torque (STT) effect in combination with the Spin-Hall-Effect (SHE) employing short current p…
Characterization of Spin-Transfer-Torque effect induced magnetization dynamics driven by short current pulses
T. Meyer, T. Brächer, F. Heussner +7
We present a time-resolved study of the magnetization dynamics in a microstructured CrHeuslerPt waveguide driven by the Spin-Hall-Effect and the Spin-Transfer-Torque effect v…
Tuning up or down the critical thickness in LaAlO3/SrTiO3 through in situ deposition of metal overlayers
D. C. Vaz, E. Lesne, H. Naganuma +4
The quasi 2D electron system (q2DES) that forms at the interface between LaAlO3 and SrTiO3 has attracted much attention from the oxide electronics community. One of its hallmark fe…
Experimental investigation of the temperature-dependent magnon density and its influence on studies of spin-transfer-torque-driven systems
Thomas Meyer, Thomas Brächer, Frank Heussner +7
We present the temperature dependence of the thermal magnon density in a thin ferromagnetic layer. By employing Brillouin light scattering and varying the temperature, an increase…
Spin-Wave versus Joule Heating in Spin-Hall-Effect/Spin-Transfer-Torque Driven Cr/Heusler/Pt Waveguides
T. Meyer, T. Brächer, F. Heussner +7
We present a time-resolved study of the DC-current driven magnetization dynamics in a microstructured Cr/Heusler/Pt waveguide by means of Brillouin light scattering. A reduction of…
Highly efficient and tuneable spin-to-charge conversion through Rashba coupling at oxide interfaces
E. Lesne, Y. Fu, S. Oyarzun +13
The spin-orbit interaction couples the electrons' motion to their spin. Accordingly, passing a current in a material with strong spin-orbit coupling generates a transverse spin cur…
Revealing the spin and symmetry properties of the buried Co2MnSi/MgO interface by low energy spin-resolved photoemission
Roman Fetzer, Marcel Lösch, Yusuke Ohdaira +8
We present a novel approach to study the spin and symmetry electronic properties of buried interfaces using low-energy spin-resolved photoemission spectroscopy. We show that this m…
Nonlinear emission of spin-wave caustics from an edge mode of a micro-structured Co2Mn0.6Fe0.4Si waveguide
T. Sebastian, P. Pirro, T. Kubota +6
Magnetic Heusler materials with very low Gilbert damping are expected to show novel magnonic transport phenomena. We report nonlinear generation of higher harmonics leading to the…
