Figure 3
Temperature-dependent magnetization of Pb5(PO4)3OHδ. ZFCW and FC magnetization as a function of temperature is given by VSM in the range of 1.8–400 K with a field of 1 kOe. The left inset shows d(MT/H)/dT as a function of temperature in the low-temperature range. The right inset shows the derivative of d(MT/H)/dT in the high-temperature range. |
