Crystal structure of NiO under high pressure

Eto, Tetsujiro*; Endo, Shoichi*; Imai, Motoharu*; Katayama, Yoshinori; Kikegawa, Takumi*

Physical Review B, 61(22), p.14984 - 14988, 2000/06

 Times Cited Count:51 Percentile:87.97(Materials Science, Multidisciplinary)

The pressure effect on the lattice constant of NiO with the rhombohedral distorted B1 structure was studied up to 141 GPa by ${em in situ}$ angle-dispersive x-ray diffraction using synchrotron radiation, an imaging plate, and a diamond anvil cell. The lattice constant $$a$$ and $$c$$, expressed in the hexagonal lattice, decrease monotonously with increasing pressure. The axial rage $$c/a$$ decreases monotonously with increasing pressure, indicating the distortion in the rhombohedral [111] direction becomes larger as pressure increases. The signiifcant change of $$c/a$$ above 60 GPa, suggested by a recent theoretical calculation, was not observed.

Crystal structure of NiO under high pressure

Eto, Tetsujiro*; Endo, Shoichi*; Imai, Motoharu*; Katayama, Yoshinori; Kikegawa, Takumi*

Science and Technology of High Pressure (Proceedings of AIRAPT-17), p.487 - 490, 2000/00

The pressure effect on the lattice constant of NiO with the rhombohedral distorted B1 structure was studied up to 141 GPa by ${em in situ}$ angle-dispersive x-ray diffraction using synchrotron radiation and an imaging plate, with reference to a recent theoretical calculation within the density-functional formalism with the local-spin density approcximation. The lattice constant $$a$$ and $$c$$, expressed in the hexagonal lattice, decrease monotonously with increasing pressure. The axial rage $$c/a$$ decreases monotonously with increasing pressure, indicating the enhancement of the rhombohedral distortion. The signiifcant change of $$c/a$$ above 60 GPa suggested by the calculation was not observed.
