Coaxial multi-layered structure is obtained when the Fe melt confined in the single-walled carbon nanotube (SWCNT) undergoes a rapid cooling. Owing to the inductive effect of the SWCNT, precursors of the long-range order (LRO) are generated in the confined Fe melt and finally been converted into local crystalline structures in the glassy Fe. A memory property has also been observed during the repeated phase transition process. Furthermore, the study of the size effect of tube diameter illustrates that the increasing diameter of the carbon tube is detrimental to the formation of local crystalline structures in nanoscale confinement.
