Abstract

The high-pressure behavior of Ni-filled and Fe-filled multiwalled carbon nanotubes has been investigated up to 27 GPa and 19 GPa, respectively, with the help of synchrotron-based angle-dispersive X-ray diffraction. These nanotubes do not show any structural transformation up to the highest pressures studied. These results are similar to that of Co-filled nanotubes [1], but are in sharp contrast to the earlier results on Fefilled tubes [2], where the tubes were found to undergo a sudden collapse of intertube separation. Our present observations suggest that the occurrence of an isostructural phase transition in $Fe_3C$, observed in our earlier study, may be responsible for the structural transition in nanotubes in that case.
