Thermomagnetic measurements of SrCo2Fe16O27, SrCoZnFe16O27 and SrZn2Fe16O27. The applied fields were, respectively, 100, 50 and 50 Oe. The temperature range covered was 300–900 K, while the shown range is limited to 325–875 K. The magnetization (in colour) and a derivative thereof (in black) are normalized versus the magnetization at 300 K as M/M300 K for easy comparison. Indications of the onset of a magnetic transition (a peak in the derivative lower than the Curie temperature) are seen for SrCo2Fe16O27 at 520 K and SrCoZnFe16O27 at 360 K.
