Tunable ultrabroadband hybrid THz emitter combining a spintronic THz source and a GaSe crystal
Afnan Alostaz, Oliver Gueckstock, Jungwei Tong +4
Linear terahertz time-domain spectroscopy (THz-TDS) is a sensitive probe for material characterization including thickness measurements of thin layers. These applications criticall…
Accessing ultrafast spin-transport dynamics in copper using broadband terahertz spectroscopy
Jiří Jechumtál, Reza Rouzegar, Oliver Gueckstock +10
We study the spatiotemporal dynamics of ultrafast electron spin transport across nanometer-thick copper layers using broadband terahertz spectroscopy. Our analysis of temporal dela…
Broadband spintronic detection of the absolute field strength of terahertz electromagnetic pulses
A. L. Chekhov, Y. Behovits, U. Martens +5
We demonstrate detection of broadband intense terahertz electromagnetic pulses by Zeeman-torque sampling (ZTS). Our approach is based on magneto-optic probing of the Zeeman torque…
Terahertz spin conductance probes of coherent and incoherent spin tunneling through MgO tunnel junctions
R. Rouzegar, M. A. Wahada, A. L. Chekhov +9
We study femtosecond spin currents through MgO tunneling barriers in CoFeB(2 nm)|MgO()|Pt(2 nm) stacks by terahertz emission spectroscopy. To obtain transport information indepe…
Nonlinear terahertz Néel spin-orbit torques in antiferromagnetic MnAu
Yannic Behovits, Alexander L. Chekhov, Stanislav Yu. Bodnar +8
Antiferromagnets have large potential for ultrafast coherent switching of magnetic order with minimum heat dissipation. In novel materials such as MnAu and CuMnAs, electric rat…
Fiber-tip spintronic terahertz emitters
Felix Paries, Nicolas Tiercelin, Geoffrey Lezier +12
Spintronic terahertz emitters promise terahertz sources with an unmatched broad frequency bandwidth that are easy to fabricate and operate, and therefore easy to scale at low cost.…
