TL;DR: In this paper, high-resolution photo-emission experiments performed with a full three-dimensional spin polarimeter provide a detailed image of the resulting spin structure, showing that the spin vector lies in the surface plane and is perpendicular to the momentum of the electrons as expected in a freeelectron model.

TL;DR: In this article, the magnetic and electronic properties of itinerant ferromagnets and their interplay have been studied by spin resolved electron spectroscopy on one hand and by high-resolution angle-resolved photoemission experiments on the other.

TL;DR: Energy distribution curves of laser-induced electron pulses from a tungsten tip have been measured as a function of tip voltage and laser power, allowing direct insight into the involved electron dynamics and revealing the temporal tunability of electron emission via the two experimental parameters.

TL;DR: In this paper, an interferometric technique based on attosecond pulse trains is applied simultaneously in a gas phase and a solid-state target to derive surface-specific photoemission delays.
