X-ray photoemission electron microscopy (XPEEM) is a full-field imaging technique giving access to the chemical state and magnetic order of laterally inhomogeneous surfaces, interfaces and thin films. In its simplest variant, synchrotronbased PEEM uses secondary emission to map local differences in the oxidation state, valence, and bond orientation around the emitter. The combination with X-ray circular and linear dichroism techniques represents the most frequent application, and has found extensive use in imaging ferromagnetic and antiferromagnetic domains. XPEEM instruments with energy filter can implement laterally resolved X-ray photoelectron spectroscopy (XPS) and angle resolved photoelectron spectroscopy (ARPES), reaching high chemical and electronic structure sensitivity. Here, we describe the basic aspects and methods of synchrotron-based spectromicroscopy with the PEEM, and its combination with low energy electron microscopy (LEEM). The present state of the art of the technique will be illustrated by applications in diverse fields, spanning from surface and materials sciences to biology and magnetism.

“…By its very nature synchrotron radiation has a well-defined time-structure with pulse lengths between 1 and 100 ps. This feature was later exploited in time-resolving XPEEM studies, the first results appearing in 2003 [11,12]. Combining high lateral and time resolution with high element selectivity and magnetic contrast, time-resolved XPEEM (TR-XPEEM) represents an extremely powerful approach for investigations of magnetodynamics at surfaces and in thin films.…”

“…Photoemission electron microscopy with pulsed excitation sources like lasers or synchrotron radiation has been evolved as a standard method for observing dynamic processes on surfaces (Bostanjoglo & Weingärtner 1997;Krasyuk et al, 2003). Recently, it has been suggested to employ high-intensity ultrashort electron beams for recording single-shot diffraction patterns or images of radiationsensitive biological objects .…”
