Engineering ultrafast spin currents and terahertz transients by magnetic heterostructures
T. Kampfrath, M. Battiato, P. Maldonado +9
In spin-based electronics, information is encoded by the spin state of electron bunches. Processing this information requires the controlled transport of spin angular momentum thro…
Spin-wave modes and band structure of rectangular CoFeB antidot lattices
Benjamin Lenk, Nils Abeling, Jelena Panke +1
We present an investigation of rectangular antidot lattices in a CoFeB film. Magnonic band structures are numerically calculated, and band gaps are predicted which shift in frequen…
Insights into ultrafast demagnetization in pseudo-gap half metals
Andreas Mann, Jakob Walowski, Markus Münzenberg +8
Interest in femtosecond demagnetization experiments was sparked by Bigot's discovery in 1995. These experiments unveil the elementary mechanisms coupling the electrons' temperature…
