抄録

The order-disorder and order-order transitions in the first-stage graphite-alkali intercalation compounds C8Rb and C8K are investigated using a lattice-gas model in the mean-field approximation. Types of transition from the disordered phase to various ordered phases are also determined by the Landau-Lifshitz theory. The present theory predicts the following three cases as possible transitions: (i) disordered phase↔a structure with a two-layer period (S2)↔a structure with a four-layer period (S4); (ii) disordered phase↔another structure with a two-layer period (S2′)↔S4; and (iii) disordered phase↔S4, where the transitions in case (i) are of second order while those in cases (ii) and (iii) are of first order.
