    • c less than 2 K and the difference in M (in 10 kOe at 20 K) less than 1 emu/g. This demonstrates that the effect of Fe impurity on the magnetic properties is negligible in the present study.

    • Chemical analysis has shown that the Al contamination from the crucible is negligibly small, 45 ppm by weight, even after heat treatment at 1450 °C.

    • For a small crystal, it is difficult to determine the oxygen content inside the bulk because of the large surface-to-volume ratio; titration techniques determine the average oxidation state of the Mn ions including the ones at the surface, and the determination of the bulk oxygen content requires additional information about the surface state, such as the terminating layer and the presence of adsorbed atoms.
