Thermoelectric power of platinum which is used as a standard. The data match well with the literature (Ref. 1). The precision is better than while absolute accuracy is better than .
Thermoelectric power of Al doped FeSi measured in natural warm-up mode. The measurement range covers from to over the temperature range of interest.
Thermoelectric power of and measured by controlling the temperature of the CCR. This demonstrates the need for measurements below liquid nitrogen temperature.
Thermoelectric power of at various magnetic fields up to 140 kOe. The unprecedented precision with the simple setup even up to 140 kOe is achieved by continuous control using a thermocouple.
Thermoelectric power of at 50 kOe for zero field cooled warming, field cooling, and field cooled warming. A hysteresis is observed across the first order ferromagnetic to antiferromagnetic transition.
Thermoelectric power of an 8 K superconductor, , at various magnetic fields. Inset shows expanded view near . Precision of better than is demonstrated.
