Popis:	The lattice constants of cubic YbInCu4 have been measured at high pressure up to 13 GPa at room temperature in order to examine the phase transition and the valence state of Yb at high pressure. It is found that the cubic structure is stable up to 13 GPa and the bulk modulus Bo and its derivative Bo1 are 112 GPa and 4.0, respectively. By comparing the present result with that of the concentrated Kondo compound YbAgCu4, the trivalent valence state of Yb in YbInCu4 is suggested to be stable up to 13 GPa at room temperature.
