Sažetak
The thermopower of the YbAl3 single crystal obtained by the “self-flux” method is reported for the first time. The characteristic temperature, T0, extracted from the temperature slope of the thermopower in the Fermi liquid regime is higher than the TFL and, moreover, higher than the TK. We point that in the papers dealing with Kondo lattice systems, the authors do not distinguish T0 and TFL and usually it is taken T0 = TFL. Also we point out that there is a great mess in notation of the characteristic temperatures and points of Kondo lattice system.
