Figure F8. Diagram showing the temperature dependence of mass susceptibility for Sample 183-1140A-37R-4, 16-18 cm, during warming from 15 to 300 K. The temperature dependence of the (A) in-phase (m') and (B) quadrature (m") mass susceptibility between 15 and 300 K was measured at five frequencies (40, 140, 400, 1000, and 4000 Hz) with AC field amplitudes between 100 and 1000 A/m.
