By blaisemouttet

There is an interest in nanoscale magnetic media for high density data storage devices. This patent from Fujitsu and Tohoku University teaches a method for coating the inner surfaces of nanotubes with magnetic or metal material for information storage and other purposes. Claims 1 and 6 read:

1. A carbon nanotube composite material comprising: a carbon nanotube; and a continuous layer of a metal covering an inner surface of the carbon nanotube, wherein the carbon nanotube is closed at one end and open at the other end.

6. A magnetic material comprising: a carbon nanotube; and a continuous layer of a magnetic metal covering an inner surface of the carbon nanotube, wherein the carbon nanotube is closed at one end and open at the other end.
