Anomalous specific heat behaviour in the quadrupolar Kondo system PrV2Al20

Masaki Tsujimoto, Yosuke Matsumoto, Satoru Nakatsuji

We have measured the specific heat of PrV${}_2$Al${}_{20}$ at very low temperatures, using high quality single crystals with the residual resistivity ratio ~ 20. The high-quality singl…
