A thorough study has been made of the physical properties under high pressure of the perovskite BaRuO3 synthesized under pressure; it includes the critical behavior in the vicinity of Tc to 1GPa and the temperature dependences of resistivity and ac magnetic susceptibility up to 8GPa. The ferromagnetism in BaRuO3 is suppressed at 8GPa. Critical fluctuations in the vicinity of Tc have been found in BaRuO3 and they are enhanced under pressure. These observations are in sharp contrast to SrRuO3 where mean-field behavior is found at Tc.
