Configurational Entropy and Possible Plateau Smaller than Rln2 in Complex Crystals

Kazuya SAITO and Yasuhisa YAMAMURA

Configurational entropy due to structural disorder in complex crystals is considered in some details. It is reminded that motional correlation and equivalence of plural entities (such as molecule or group) have potentially serious effects on the entropy. Possible appearance of entropy plateaus in its temperature dependence is suggested.
