Terahertz switching of antiferromagnetic order by Néel spin-orbit torques
Yannic Behovits, Alexander L. Chekhov, Amon Ruge +13
Ultrafast electric manipulation of magnetic order in solids is critical for the development of future terahertz data processing. A fascinating concept for such high-speed operation…
All-optical magnetometric characterization of the antiferromagnetic exchange-spring system MnAu|Py by terahertz spin-torques
Yannic Behovits, Alexander L. Chekhov, Bruno Rosinus Serrano +6
Antiferromagnetic materials have great potential for spintronic applications at terahertz (THz) frequencies. However, in contrast to ferromagnets, experimental studies of antiferro…
Rotating spintronic terahertz emitter optimized for microjoule pump-pulse energies and megahertz repetition rates
Alkisti Vaitsi, Vivien Sleziona, Luis E. Parra López +7
Spintronic terahertz emitters (STEs) are powerful sources of ultra-broadband single-cycle terahertz (THz) field transients. They work with any pump wavelength, and their polarity a…
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…
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…
Spin-voltage-driven efficient terahertz spin currents from the magnetic Weyl semimetals CoMnGa and CoMnAl
Genaro Bierhance, Anastasios Markou, Oliver Gueckstock +7
Magnetic Weyl semimetals are an emerging material class that combines magnetic order and a topologically non-trivial band structure. Here, we study ultrafast optically driven spin…
Optically gated terahertz-field-driven switching of antiferromagnetic CuMnAs
J. J. F. Heitz, L. Nádvorník, V. Balos +11
We show scalable and complete suppression of the recently reported terahertz-pulse-induced switching between different resistance states of antiferromagnetic CuMnAs thin films by u…
Ultrafast demagnetization of iron induced by optical vs terahertz pulses
A. L. Chekhov, Y. Behovits, J. J. F. Heitz +7
We study ultrafast magnetization quenching of ferromagnetic iron following excitation by an optical vs a terahertz pump pulse. While the optical pump (photon energy of 3.1 eV) indu…
