摘要：

The gamma-alpha transition in Ce0.8La0.1Th0.1 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 is quantitatively reproduced by a model that invokes the field and temperature dependence of the entropy of the 4f-electron moments of the gamma phase.
