Giant Sommerfeld coefficient in the heavy-fermion YbBiPt
Abstract
It has been derived that the Sommerfeld coefficient γ as large as 25 J/K2mol can be theoretically accounted for provided the charge f-electron fluctuations are substantially suppressed. This result enables the understanding of the heavy-fermion YbBiPt (γ =8 J/K2mol) as the spin fluctuator and should stimulate the experimental specific-heat research at low temperatures.
