"Особенности плавления и кристаллизации сплава Na-K, введенного в нанопористые матрицы"

23 Na NMR studies of the Na-K eutectic alloy embedded into porous glass with 7 nm pores showed that melting of
Na2K confined nanoparticles is a continuous process with smooth changes in the Knight shift of a narrow resonance
line and nuclear spin relaxation between those in the crystalline and liquid states. The intermediate state which
occurs upon melting is stable and more favorable than the liquid state. The inverse freezing transformation can
be sharp as at a first order transition or continuous depending on the initial temperature of cooling. The results
suggest revision of theoretical predictions for the melting and freezing transitions in confined geometry.
