26. We note that these measurements are sensitive to the average direction of CoO AFM spins. While a small number of CoO spins in different directions would not be detected, it would be expected that a number of the nearby CoO spins should display a sizeable twisting toward the average direction, leading to an increase the spin-flip scattering beyond that observed.
