Magnetism, transport and atomic structure of amorphous binary YxCo1-x alloys
Zexiang Hu, Jean Besbas, Katarzyna Siewierska +3
Sputtered thin films of binary YxCo1-x with 0 < x < 0.54 and thickness 15 nm are investigated to help understand the ferromagnetism of cobalt in amorphous rare-earth cobalt alloys.…
Au4Mn, a localized ferromagnet with strong spin-orbit coupling, long-range ferromagnetic exchange and high Curie temperature
Yangkun He, Zsolt Gercsi, Rui Zhang +8
Metallic Mn-based alloys with a nearest-neighbor Mn-Mn distance greater than 0.4 nm exhibit large, well-localized magnetic moments. Here we investigate the magnetism of tetragonal…
Single-pulse all-optical switching in amorphous DyCo and TbCo
Zexiang Hu, Jean Besbas, Ross Smith +5
Repeated uniform switching of the magnetization of thin films of ferrimagnetic amorphous Gd(FeCo) in response to single fast laser pulses is well established. Here we…
Ultra-fast Double Pulse All-Optical Re-switching of a Ferrimagnet
C. Banerjee, K. Rode, G. Atcheson +4
All-optical re-switching has been investigated in the half-metallic Heusler ferrimagnet Mn2Ru0.9Ga, where Mn atoms occupy two inequivalent sites in the XA-type structure. The effec…
Magnetization dynamics of the compensated ferrimagnet
G. Bonfiglio, K. Rode, K. Siewerska +7
Here we study both static and time-resolved dynamic magnetic properties of the compensated ferrimagnet from room temperature down to 10K, thus crossing the magnetic compensation te…
Single pulse all-optical toggle switching of magnetization without Gd: The example of Mn2RuxGa
C. Banerjee, N. Teichert, K. Siewierska +6
Energy-efficient control of magnetization without the help of a magnetic field is a key goal of spintronics. Purely heat-induced single-pulse all-optical toggle switching has been…
Direct visualization of current induced spin accumulation in topological insulators
Yang Liu, Jean Besbas, Yi Wang +10
Charge-to-spin conversion in various material systems is the key for the fundamental understanding of spin-orbitronis as well as the development of efficient means to manipulate th…
Room-temperature nanoseconds spin relaxation in WTe2 and MoTe2 thin films
Qisheng Wang, Jie Li, Jean Besbas +11
The Weyl semimetal WTe2 and MoTe2 show great potential in generating large spin currents since they possess topologically-protected spin-polarized states and can carry a very large…
Helicity dependent photovoltaic effect in Bi2Se3 under normal incident light
Jean Besbas, Karan Banerjee, Jaesung Son +7
Topological insulators (TIs) form a new class of materials with insulating bulk and surface conduction ensured by topologically protected surface states (TPSS). We investigate the…
Spin orbit torques and Dzyaloshinskii-Moriya interaction in dual-interfaced Co-Ni multilayers
Jiawei Yu, Xuepeng Qiu, Yang Wu +5
We study the spin orbit torque (SOT) and Dzyaloshinskii-Moriya interaction (DMI) in the dual-interfaced Co-Ni perpendicular multilayers. Through the combination of top and bottom l…
Biexciton, single carrier, and trion generation dynamics in single-walled carbon nanotubes
Bertrand Yuma, Stéphane Berciaud, Jean Besbas +10
We present a study of free carrier photo-generation and multi-carrier bound states, such as biexcitons and trions (ionized excitons), in semiconducting single-walled carbon nanotub…
