Superdiffusive Spin Transport as a Mechanism of Ultrafast Demagnetization
TL;DR: A semiclassical model for femtosecond laser-induced demagnetization due to spin-polarized excited electron diffusion in the superdiffusive regime is proposed and it is shown that this mechanism accounts for the experimentally observed demagnetsization within 200 fs in Ni, without the need to invoke any angular momentum dissipation channel.
Journal ArticleDOI
Terahertz spin current pulses controlled by magnetic heterostructures.
Tobias Kampfrath,Marco Battiato,Pablo Maldonado,Gerrit Eilers,Jan Nötzold,S. Mahrlein,Vladyslav Zbarsky,Frank Freimuth,Yuriy Mokrousov,Stefan Blügel,Martin Wolf,Iuliana Radu,Peter M. Oppeneer,Markus Münzenberg +13 more
TL;DR: It is demonstrated, by experiment and theory, that the temporal shape of femtosecond spin current bursts can be manipulated by using specifically designed magnetic heterostructures, which opens the door to engineering high-speed spintronic devices and, potentially, broadband terahertz emitters.
Journal ArticleDOI
Ultrafast magnetization enhancement in metallic multilayers driven by superdiffusive spin current
Dennis Rudolf,Chan La-o-vorakiat,Marco Battiato,Roman Adam,Justin M. Shaw,Emrah Turgut,Pablo Maldonado,Stefan Mathias,Stefan Mathias,Patrik Grychtol,Hans T. Nembach,Thomas J. Silva,Martin Aeschlimann,Henry C. Kapteyn,Margaret M. Murnane,Claus M. Schneider,Peter M. Oppeneer +16 more
TL;DR: In this paper, the spin dynamics in magnetic trilayers can be driven by ultrafast light pulses, resulting in transient magnetization changes on femtosecond timescales.

TL;DR: Spatially separate the spin dynamics using Ni/Ru/Fe magnetic trilayers and surprisingly find that optically induced demagnetization of the Ni layer transiently enhances the magnetizations of the Fe layer when the two layer magnetizations are initially aligned parallel.

Ultrafast spin transport as key to femtosecond demagnetization
A. Eschenlohr,Marco Battiato,Pablo Maldonado,Niko Pontius,Torsten Kachel,Karsten Holldack,Rolf Mitzner,Alexander Föhlisch,Alexander Föhlisch,Peter M. Oppeneer,Christian Stamm +10 more
TL;DR: It is demonstrated that direct laser irradiation is in fact not essential for ultrafast demagnetization, and that electron cascades caused by hot electron currents accomplish it very efficiently.
