Times Cited Count：8 Percentile：53.1(Instruments & Instrumentation)Usually, X-ray diffraction experiments under strong magnetic fields are carried out using a superconducting magnet and the maximum field is limited up to 15T. In order to overcome this limitation, we have constructed an X-ray diffraction system combined with a pulsed magnet. The structural phase transition of Pr

MnO
around 8 T and the valence transition of YbInCu
around 26 T are shown as a demonstration.

Times Cited Count：7 Percentile：49.56(Instruments & Instrumentation)It is well know that many substances have different structures in the crystalline state and they exhibit first-order structural phase transitions by a change in pressure. On the other hand, pressure-induced structural changes in the liquid and glassy states were supposed to be monotonous. The recent development of synchrotron radiation sources enables us to perform structural studies on liquids and glasses under high pressure and high temperature conditions. These studies revealed that the changes in the liquid and glassy states are not necessarily monotonous. We will present recent results on liquid phosphorus and silica glass.
