  Title Thermodynamical analysis of the magnetic phase diagrams of Ce systems Type Journal Article
  Year 2001 Publication Journal of the Physical Society of Japan Abbreviated Journal J. Phys. Soc. Japan  
  Volume 70 Issue 7 Pages 2139-2150

  Abstract Three types of magnetic phase diagrams as a function of composition or pressure, f (z, p), are identified among Ce systems: I) with the ordering temperature T-ord --> 0 monotonously, followed by a narrow region where non-Fermi-liquid (NFL) behavior is observed; II) with T-ord vanishing at finite temperature, but followed by an extended NFL region, and III) where T-ord remains nearly constant. Among the analyzed systems intrinsic differences are found in the evolution of their respective properties, namely: in group-1 an increase of the density of excitations is observed below T-ord. In group-II the evanescense of T-ord(z, p) coincides with the extrapolation to zero of the magnetic free energy (DeltaG --> 0), and the existence of a reference function implying that T-K not equal f (z, p), whereas T-ord = f (z, p). Finally, group-III is also characterized by the evanescense of T-ord where DeltaG --> 0, but in this case T-ord not equal f (z, p) whereas T-K = f (z, p). The characteristics of each group are discussed and compared together with the different C-p(T)/T dependencies at T greater than or equal to T-ord and some related scalings, which allow to recognize a quasi-paramagnetic phase.
