Non-Fermi Liquid Behavior in Dilute Quadrupolar System Pr${}_x$La${}_{1-x}$Pb${}_3$ with $x$$\le$0.05

Tatsuya Kawae, Tatsuharu Yamamoto, Kenji Yurue +3

We have studied the low-temperature properties of Pr${}_x$La${}_{1-x}$Pb${}_3$ with non-Kramers ${\Gamma }_3$ quadrupolar moments of the crystal-electric-field ground state, for a wide con…
