title: Premelting phenomena in ionic crystals.
abstract: The theory of the premelting phenomena in ionic crystals has been developed on the basis of the concept of heterophase fluctuation in the vicinity of their melting points. The size of the liquid-like clusters is estimated by the theory using the experimental specific heat value. Molecular dynamics simulations are also performed in NaCl and AgBr crystals to examine the ionic configuration in the premelting region. The structural features are discussed using the Lindemann instability criterion.
