Figure F7. Diagram showing the temperature dependence of mass susceptibility for Sample 183-1141A-24R-2, 6-8 cm, during warming from 15 to 225 K. The temperature dependence of the (A) in-phase (m´) and (B) quadrature (m'') mass susceptibility between 15 and 225 K was measured at five frequencies (40, 140, 400, 1000, and 4000 Hz), with AC field amplitudes between 100 and 1000 A/m.
