高圧下における遷移金属酸化物の単結晶育成

抄録

We have developed a new method to grow single crystals of transition metal oxides under high pressures of several GPa, using a cubic anvil press. Here in situ observations of the reactions under high pressures are performded by synchrotron powder X-ray diffrraction, to find out the optimum crystal growth conditions. We have succeeded in growing single crystals of various transition metal oxides such as PrNiO₃ and the high pressure phase of (VO)₂P₂O₇. We thus expect that the present high pressure technique plays more and more important roles to develop studies using single crystalline samples.
