利用重整化群和自洽重整化自旋涨落模型，分析了公式（x = 0和x = 0.05）接近磁不稳定性的重费米子系统的低温热膨胀。将使用重正化费米温度计算出的格鲁内森参数与根据热膨胀测量和先前获得的比热数据确定的有效参数进行比较。
The low-temperature thermal expansion of the heavy-fermion system with the formula (x = 0 and x = 0.05) close to the magnetic instability is analysed in terms of the renormalization group and self-consistent renormalized spin-fluctuation models. The Gruneisen parameter calculated using the renormalized Fermi temperature is compared with the effective one which is determined from thermal expansion measurements and previously obtained specific heat data.
