Heat Capacity of needle-like [length=5mm, diameter=1 mm] β-FeSi2​
single crystal, grown by chemical vapor transport has been measured. Two
anomalies are found, a broad deviation centered around 160 K and a clear
deviation at a temperature of 255 K approximately. We have attempted to relate
these to the anomalies previously reported in the case of the resistivity data.
The Transient Thermoelectric Effect [TTE] results lead us to the inference that
the system under goes from single carrier system to at least two carrier system
at 220 K-our heat capacity results seem to provide further independent evidence
for this transition in this system.Comment: 8 pages, 5 figure
