Verification of the Wiedemann-Franz law in YbRh2Si2 at a quantum critical point
Y. Machida, K. Tomokuni, K. Izawa +4
The thermal conductivity measurements have been performed on the heavy-fermion compound YbRh2Si2 down to 0.04 K and under magnetic fields through a quantum critical point (QCP) at…

Thermoelectric response near a quantum critical point of beta-YbAlB4 and YbRh2Si2: A comparative study
Y. Machida, K. Tomokuni, C. Ogura +7
The thermoelectric coefficients have been measured on the Yb-based heavy fermion compounds beta-YbAlB4 and YbRh2Si2 down to a very low temperature. We observe a striking difference…
