What is Mild synthesis of CoFe2O4 nanowires using carbon nanotube template: a high-coercivity material at room temperature about?

The synthesis under mild conditions, i.e. 100 C and atmospheric pressure, of magnetic CoFe 2 O 4 nanowires with an average diameter of 50 nm and lengths up to several micrometers encapsulated inside multi-walled carbon nanotubes with a high yield filling was performed using the confinement effect provided by the surrounding carbon walls, each nanotube being considered as a single nanoreactor. A material with high coercivity at room temperature for small particles was obtained by submitting the CoFe 2 O 4 nanowires to an Ar treatment at 550 C for 2 h.
