标题： Suppression of the $γ-α$ structural phase transition in $Ce_{0.8} La_{0.1} Th_{0.1}$ by large magnetic fields

摘要： Ce$_{0.8}$La$_{0.1}$Th$_{0.1}$中的$\gamma-\alpha$转变通过电阻率和磁化率随外加磁场的变化进行测量。 $\gamma - \alpha$转变温度随着磁场的增加而降低，在约56特斯拉时达到零温度。转变温度的磁场依赖性可以用一个模型进行拟合，该模型涉及$4f$电子矩在$\gamma$相中的磁场和温度依赖性，表明Ce及其合金中的体积塌陷主要由熵的因素驱动。 显示英文摘要

摘要： The $\gamma-\alpha$ transition in Ce$_{0.8}$La$_{0.1}$Th$_{0.1}$ is measured as a function of applied magnetic field using both resistivity and magnetization. The $\gamma - \alpha$ transition temperature decreases with increasing magnetic field, reaching zero temperature at around 56 T. The magnetic-field dependence of the transition temperature may be fitted using a model that invokes the field and temperature dependence of the entropy of the $4f$-electron moments of the $\gamma$ phase, suggesting that the volume collapse in Ce and its alloys is primarily driven by entropic considerations.
