Single‐crystalline AlGaN:Mn nanotubes (see figure) with a an outer diameter less than 200 nm and a length of a few micrometers are prepared by a chloride‐based chemical vapor deposition process. The nanotubes exhibit room‐temperature ferromagnetism without evidence of a ferromagnetic transition, showing that the structural and compositional modulation of 1D nanostructures could open up a way of exploring new classes of diluted magnetic semiconductors.
