The experiments were performed with the approval of JASRI (Proposal Nos. 2006B1236, 2007A1117, 2007B1739, 2008A1298, 2009A1755, 2009B1415, 2009B1736, 2009B2120, 2010A1645, 2010B1157, 2010B1639, 2010B1709, 2011A1183, 2011A1377, 2011A1657 and 2011A2056). Some of the time-resolved systems were developed during beamtime at other beamlines of SPring-8 (Proposal Nos. 2007A1317, 2007B1641, 2009B1558, 2010A1318 and 2010B1411). This research was partially supported by a Grant-in Aid for Scientific Research (S, 18101004 ) from the Japan Society for the Promotion of Science . The permalloy dots were fabricated by Profs. T. Kimura, Y. Otani, S. Matsui and Y. Haruyama. We are indebted to Drs. K. Kodama, T. Kudo and Prof. A. Kakizaki for their experimental support.

N2 - The present status and the recent progress of pump-probe time-resolved photoemission electron microscopy at SPring-8 are introduced. Combining the variety of bunch operation modes available at the SPring-8 storage ring with ultra-short excitation sources including pulsed magnetic fields, electric fields and lasers, the element-specific time evolution of materials in response to the excitation can be observed with spatial and temporal resolutions of (50-300) nm and (40-100) ps, respectively, with repetition frequencies of up to 42 MHz. By using the magnetic circular dichroism effect, the domain motion of sub-micron sized magnetic areas can be observed. The time evolution of electronic structures in local areas can also be studied. The experimental setups and representative activities are described.
