Transport properties of Yb0.8Y0.2InCu4 under high pressure

Abstract We report electrical resistivity of Yb 0.8 Y 0.2 InCu 4 as a function of temperature down to 0.1 K and pressure up to 2.1 GPa . As the valence transition temperature approaches zero temperature with applying pressure, an inflection point associated with weak ferromagnetic ordering is observed. The Curie temperature is insensitive to pressure up to 2.1 GPa . On the other hand, we observe no evidence of superconducting behavior for the present sample.
