- Supertransferred hyperfine interactions between the $Cu^{2+}$ unpaired electron and the $\text{}^{105}Pd$ nuclei in the $Sr_2Pd_{0.99}Cu_{0.01}O_3$ ceramic were studied by the EPR method. The spectrum of isolated -Pd-O-$CuO_2$-O-Pd- units ($g_∥$ = 2.280±0.001; $g_⊥$ = 2.040±0.001; $A_∥(\text{}^{63}Cu)$ = 13 mT±0.1; $A_∥(\text{}^{65}Cu)$ = 13.9 ±0.1 mT; $A_⊥(\text{}^{63,65}Cu)$ = 0.0 mT) overlaps the signal from small groups of exchange coupled $Cu^{2+}$ ions ($g_∥$ = 2.278±0.002; $g_⊥$ = 2.041±0.001). The isotropic contribution was shown to dominate in the Cu-Pd supertransferred interactions ($A_∥(\text{}^{105}Pd) = A_⊥ (\text{}^{105}Pd)$ = 1 mT = $a_\text{iso}$ Pd).
