APS Colloquium 2004

The monthly APS Colloquium series is intended for the benefit of the Advanced Photon Source community as well as the Argonne community by bringing distinguished scientists in all disciplines to lecture on topics of general interest.  Objectives include the cross-fertilization of research initiatives at various institutions and the identification of possible uses of the Advanced Photon Source.  The lecturer is also invited to spend an additional day visiting with scientists at Argonne.

An integrated video and slides presentation, created using SofTV, is available for some colloquium. SofTV requires Netscape 7.1+ or IE 6.0+. If you do not meet the SofTV viewer requirements, Real video and PDF slides of the presentation are also provided.

The movie shows the phase transition from the low temperature ferromagnetic phase to the high temperature paramagnetic phase. Initially two magnetic domains with the magnetization pointing horizontally in opposite directions are seen. During the transition vertical paramagnetic regions nucleate and develop into stripes whose width grows with increasing temperature. Simultaneously domains with opposite magnetization develop in the originally large domains and rearrange with decreasing width of the ferromagnetic stripes. The sample drifts somewhat during heating.Microscopy with slow electrons: from LEEM to XPEEM (Sept. 8)
