对YbBiPT的电阻率、磁阻、交流和直流磁化率以及比热的测量表明，该化合物是一个非常重电子的体系。8J/k2(摩尔Yb)的低温Sommerfeld系数不受0.4K相变的影响。我们认为YbBiPT中的重质量态是由低载流子浓度的电子子系统中的Bloch态发展而来的，这是不同寻常的。
Measurements of the electrical resistivity, magnetoresistance, ac and dc magnetic susceptibility, and specific heat on YbBiPt indicate this compound to be a very heavy-electron system. The low-temperature Sommerfeld coefficient of 8 J/K2 (mole Yb) is not affected by a phase transition at 0.4 K. We suggest that the heavy-mass state in YbBiPt is unconventional in that it develops from Bloch states in an electronic subsystem with low carrier concentration.
