High pressure experiments were performed with deuterated ice VII using diamond anvil cell in a pressure range of 0.1 MPa to 60 GPa at room temperature in order to further understanding a long-argued issue of phase change in ice VII at approximatel...

Compressed calcium exhibits successive structural transitions: face-centered cubic (Ca-I)→body-centered cubic (Ca-II)→simple cubic (Ca-III)→P41212(Ca-IV)→Cmca(Ca-V). We performed x-ray diffraction measurements of calcium at pressure up to 172 GPa ...

The recently discovered high pressure phase VII of calcium [M. Sakata et al., Phys. Rev. B 83, 220512(R) (2011)] has the highest superconducting transition temperature (Tc) of 29 K among all the elements. Understanding the cause for such a high Tc...

An angular dispersive X-ray diffraction experiment on calcium metal (Ca) has been performed at high pressures up to 158 GPa. Ca forms an fcc lattice at ambient conditions and transforms to a bcc lattice at 20 GPa and to a simple cubic lattice (sc)...
