The hyperfine magnetic field $H_{\text{HF}}$ at 55Mn in ferromagnetically ordered double perovskites La1-xBixMn0.5Ni0.5O3 with $0 \leq x \leq 0.9$ were investigated by NMR at 1.8 K. $H_{\text{HF}}$ decreases with increasing Bi content $x$ from $-258$ kOe at $x = 0$ to approximately $-280$ kOe at $x = 0.9$, which is attributed to a reduction in the positive supertransferred hyperfine magnetic field, $H_{\text{STHF}}$, from neighboring Ni2+ ions. The reduction in $H_{\text{STHF}}$ caused by the Bi substitution suggests that the covalent character of Ni2+–O2-–Mn4+ bonds decreases in competition with that of Bi3+–O2- bonds. The decrease in the ferromagnetic Curie temperature of the present system with increasing $x$ is quantitatively interpreted with the decreasing covalent character of Ni2+–O2-–Mn4+ bonds.
