Abstract: The X-ray diffraction, Mössbauer, calorimetric, and magnetic characteristics of zirconolite GdFeTi$_2$O$_7$ have been measured to determine the ground magnetic state. A kink dependent on the magnetic prehistory of the sample has been revealed in the temperature dependence of the magnetic moment at $T$ = 3 K. Mössbauer spectroscopy has confirmed the nonequivalence of the iron ion positions in GdFeTi$_2$O$_7$. The experimental data obtained allow the conclusion on the formation of a spin glass state with the freezing temperature $T_f$ = 3 K in the GdFeTi$_2$O$_7$ compound.
