摘要：
X-ray powder diffraction has been studied on Ce(Ru0.85Rh0.15)(2)Si-2 between 300 and 4 K under pressure up to 32 GPa with a diamond anvil cell, and the lattice constants and the bulk modulus have been obtained. The bulk modulus shows a rapid drop between 100 and 50 K; when the temperature decreases from 300 to 4 K: This tendency is most likely attributed to Kondo effect and/or a sign of a spin density wave.
