The Hall effect has been investigated using single crystals of the frustrated Kondo lattice Pr₂ Ir₂ O₇. The transverse Hall resistivity ρ_xy is found to increase logarithmically on cooling below 1 K where the spin liquid behavior has been observed. At the same temperature range, the longitudinal resistivity has nearly no temperature dependence. The magnetic field dependence of ρ_xy shows nonlinear increase against the magnetization. This behavior cannot be ascribed to the conventional mechanism such as skew scattering and side-jump processes.
