We report the influence of external pressure on the temperature dependence of magnetization and electrical resistivity as well as high-resolution photoemission studies for an alloy, Ce2Rh(0.7)Co(0.3)Si3, ordering magnetically below 3 K. It is found that the external pressure has the same effect as that induced by (further) Co substitution for Rh in the series, Ce2Rh(1-x)Co(x)Si3, resulting in qualitative changes in the features in the magnetic and transport data, with a suppression of magnetic ordering followed by quantum critical point effect. The high-resolution spectra reveal signature of Kondo feature at ambient feature. These findings support the validity of spin-density-wave picture in this series.
