Polarized phonons carry the missing angular momentum in femtosecond demagnetization
S. R. Tauchert, M. Volkov, D. Ehberger +8
Magnetic phenomena are ubiquitous in our surroundings and indispensable for modern science and technology, but it is notoriously difficult to change the magnetic order of a materia…
Highly coherent electron beam from a laser-triggered tungsten needle tip
Dominik Ehberger, Jakob Hammer, Max Eisele +4
We report on a quantitative measurement of the spatial coherence of electrons emitted from a sharp metal needle tip. We investigate the coherence in photoemission using near-ultrav…
A tip-based source of femtosecond electron pulses at 30keV
Johannes Hoffrogge, Jan-Paul Stein, Michael Krüger +5
We present a nano-scale photoelectron source, optimized towards ultrashort pulse durations and well-suited for time-resolved diffraction experiments. A tungsten tip, mounted in a s…
