Manipulating THz Spin Current Dynamics by the Dzyaloshinskii-Moriya Interaction in Antiferromagnetic Hematite
Hongsong Qiu, Tom Sebastian Seifert, Lin Huang +12
An important vision of modern magnetic research is to use antiferromagnets as controllable and active ultrafast components in spintronic devices. Hematite is a promising model mate…
Emission of coherent THz magnons in an antiferromagnetic insulator triggered by ultrafast spin-phonon interactions
E. Rongione, O. Gueckstock, M. Mattern +17
Antiferromagnetic materials have been proposed as new types of narrowband THz spintronic devices owing to their ultrafast spin dynamics. Manipulating coherently their spin dynamics…
Circular photogalvanic effects in topological insulator/ferromagnet hybrid structures
T. Schumann, T. Kleinke, L. Braun +12
We study laser driven spin-current effects at ferromagnet/topological-insulator interfaces by two complementary experimental approaches. The DC photocurrent is studied in ferromagn…
Atomic scale control of spin current transmission at interfaces
Mohamed Amine Wahada, Ersoy Sasioglu, Wolfgang Hoppe +7
Spin transmission at ferromagnet/heavy metal interfaces is of vital importance for many spintronic devices. Usually the spin current transmission is limited by the spin mixing cond…
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…
