Experimental evidence of inertial dynamics in ferromagnets
Kumar Neeraj, Nilesh Awari, Sergey Kovalev +17
The understanding of how spins move at pico- and femtosecond time scales is the goal of much of modern research in condensed matter physics, with implications for ultrafast and mor…
Finite size effects on the ultrafast remagnetization dynamics of FePt
L. Willig, A. von Reppert, M. Deb +3
We investigate the ultrafast magnetization dynamics of FePt in the L10 phase after an optical heating pulse, as used in heat assisted magnetic recording. We compare continuous and…
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.…
Antiferromagnetic Domain Wall Control via the Surface Spin Flop in Fully Tunable Synthetic Antiferromagnets with Perpendicular Magnetic Anisotropy
Benny Böhm, Lorenzo Fallarino, Darius Pohl +4
Antiferromagnetic (AF) domain walls have recently attracted revived attention, not only in the emerging field of AF spintronics, but also more specifically for offering fast domain…
Ultrafast X-Ray Induced Changes of the Electronic and Magnetic Response of Solids Due to Valence Electron Redistribution
Daniel J. Higley, Alex H. Reid, Zhao Chen +13
We report a novel mechanism, consisting of redistribution of valence electrons near the Fermi level, during interactions of intense femtosecond X-ray pulses with a Co/Pd multilayer…
Magnonic band structure in a Co/Pd stripe domain system investigated by Brillouin light scattering and micromagnetic simulations
Chandrima Banerjee, Pawel Gruszecki, Jaroslaw W. Klos +3
By combining Brillouin Light Scattering and micromagnetic simulations we studied the spin-wave dynamics of a Co/Pd thin film multilayer, features a stripe domain structure at reman…
