Besides the step-like decreases of \\kappa at the field-induced transitions from the spin-ice state to the kagom\\'e-ice state and then to the polarized state, an abnormal phenomenon is that the \\kappa(H) isotherms show a clear irreversibility at very low temperatures upon sweeping magnetic field up and down. This phenomenon surprisingly has no correspondence with the well-known magnetization hysteresis.
