Ultrafast coherent all-optical switching of an antiferromagnet with the inverse Faraday effect
Tobias Dannegger, Marco Berritta, Karel Carva +4
We explore the possibility of ultrafast, coherent all-optical magnetization switching in antiferromagnets by studying the action of the inverse Faraday effect in CrPt, an easy-plan…
Frequency-independent terahertz anomalous Hall effect in DyCo, CoFe and GdFe thin films from DC to 40 THz
Tom S. Seifert, Ulrike Martens, Florin Radu +11
The anomalous Hall effect (AHE) is a fundamental spintronic charge-to-charge-current conversion phenomenon and closely related to spin-to-charge-current conversion by the spin Hall…
Distinguishing Local and non-Local Demagnetization in Ferromagnetic FePt Nanoparticles
Patrick W. Granitzka, Alexander H. Reid, Jerome Hurst +21
Time-resolved coherent X-ray diffraction is used to measure the spatially resolved magnetization structure within FePt nanoparticles during laser-induced ultrafast demagnetization.…
Magneto-optical properties of Au upon the injection of hot spin-polarized electrons across Fe/Au(001) interfaces
A. Alekhin, I. Razdolski, M. Berritta +7
We demonstrate a novel method for the excitation of sizable magneto-optical effects in Au by means of the laser-induced injection of hot spin-polarized electrons in Au/Fe/MgO(001)…
Unified theory of magnetization dynamics with relativistic and nonrelativistic spin torques
Ritwik Mondal, Marco Berritta, Peter M. Oppeneer
Spin torques play a crucial role in operative properties of modern spintronic devices. To study current-driven magnetization dynamics, spin-torque terms providing the action of spi…
Ultrafast demagnetization of Pt magnetic moment in L1-FePt probed by hard x-ray free electron laser
Kohei Yamamoto, Yuya Kubota, Motohiro Suzuki +15
We demonstrate ultrafast magnetization dynamics in a 5d transition metal using circularly-polarized x-ray free electron laser in the hard x-ray region. A decay time of light-induce…
