| 内容記述 | The effects of pressure and temperature on the lattice constants and thermal expansion coefficients of Indium were studied up to 18.6 GPa and 506 K by using in situ X-ray diffraction method with an externally heated diamond anvil cell. Indium exhibits a tetragonal structure. The measured c/a ratio of tetragonal structure decreases with increasing temperature and its temperature dependence decreases with increasing pressure. The thermal expansion coefficient of the a-axis also decreases with increasing pressure up to 7 GPa and remains almost constant above 7 GPa, whereas that of the c-axis increases monotonously with pressure and changes from negative to positive at around 7 GPa. The observed behavior suggests that temperature reduces the tetragonal distortion of indium, and its effect is dominant below 7 GPa; in contrast, pressure enhances lattice distortion, and tends to have a stronger effect above 7 GPa. | |||||
