Synchrotron X-ray experiments in pulsed high magnetic fields.

Recent developments of the techniques for measurements of X-ray diffraction and X-ray absorption spectroscopy in very high magnetic fields are reviewed. Miniature pulsed magnets allow us to conduct various kinds of high-field X-ray experiments rather easily; the magnets can be readily installed on a conventional apparatus such as a diffractometer and a cryostat because of its smallness. The results of some experiments on the field-induced phase transition of a rare-earth intermetallic compound (YbInCu4) are also presented.
