Advantages to conversion of lattice heat capacity to C-V in the resolution of excess properties - The Ln(2)S(3)'s as an example Academic Article uri icon

abstract

  • This paper represents a fitting (modeling) of the temperature dependence of the Komada-Westrum characteristic temperature for those -, - and -phase lanthanide sesquisulfides for which the total heat capacities, including internal degrees of freedom (e.g., Schottky and magnetic contributions), were connected to the residue of only lattice vibrations yielding lattice heat-capacity contributions. These characteristic temperatures (KW) at 298.15 K are seen to behave smoothly (nearly linearly) as a function of (cationic) atomic number within the region of stability of each phase as does the density. The trends between the phases also show some consistency but not predictability of one from the other.
