Perturbed angular correlation (PAC) measurements have been carried out in the antiferromagnetic GdCrO 3 perovskite oxide using 111 In ( 111 Cd) and 181 Hf( 181 Ta) nuclear probes. The radioactive parent nuclei 111 In and 181 Hf were introduced in the compound through a chemical process during sample preparation. The PAC measurements were carried out in the temperature range 20-300 K. Measurements with the 181 Ta indicated a unique quadrupole interaction above 170 K and a combined electric quadrupole and magnetic dipole interactions below this temperature. The observed interaction was assigned to the probe nuclei substituting Cr sites. Measurements with 111 Cd showed two quadrupole interactions. Only one of the fractions however, showed a combined electric and magnetic interaction in the temperature rage 20-170 K which was assigned to 111 Cd probe substituting Cr site. The other fraction was attributed to the Gd site. The present results are compared with those of LaCrO 3 and NdCrO 3 .
