    • If the ferromagnetic transition temperature is defined as the temperature where the net ferromagnetic moment disappears, all compositions of La0.67Ba0.33MnOz for 2.85⩽z⩽2.99 have essentially the same Tc of 280–330 K.

    • We believe that the films previously reported to have a large magnetoresistance are oxygen deficient. In addition to the oxygen deficiency, the degree of crystallinity and uniformity of oxygen distribution contribute to the large MR effect in the films.

    • For polycrystal samples, the magnetic domain size may be limited by polycrystal size in the sample. We assume that the magnetic domain size is roughly the same as the polycrystal size.
