Abstract
Using the expression by Trivedi in the high-temperature limit with nearest-neighbour central-force interaction, the anharmonic contributions to the specific heat of the alkali alloys are studied theoretically. The concentration x-dependence of the anharmonic coefficient for the specific heat A, defined by CΩ/3Nk = 1 + AT, is calculated for CS1−xKx, CS1−xRbx, and Rb1−xKx solid solutions.
Mit dem Ausdruck von Trivedi im Grenzfall hoher Temperaturen fur Zentralkraftwechselwirkung nachster Nachbarn werden die anharmonischen Beitrage zur spezifischen Warme der Alkali-Legierungen theorethisch untersucht. Die x-Konzentrationsabhangigkeit der anharmonischen Koeffizienten der spezifischen Warme A. definiert durch CΩ/3Nk = 1 + AT, wird fur Cs1−xKz, Cs1−xRbx. und Rb1−xkz Legierungen berechnet.
