New High‐Temperature Dependence of Magnetic .
High‐temperature‐dependent susceptibility (χ‐T) measurements were performed using a KLY‐3 Kappabridge with a CS‐4 high‐temperature furnace. For bulk measurement, the KLY‐3 modular system has a sensitivity of 3 × 10 −8 SI to susceptibility changes, and the CS‐4 temperature control unit has a temperature accuracy of ±2 °C.
