Image of FIG. 1.
FIG. 1.

(a) SEM image of high-density nanowires grown on the substrates. (b) TEM image shows the nanowires having the diameter . (c) TEM image for a MnO nanowire and its (d) atomic-resolved image showing single-crystalline cubic MnO crystal. ED pattern confirms the [100] growth direction (inset). (e) TEM image for a nanowire and its (f) atomic-resolved image showing single-crystalline tetragonal crystal. ED pattern confirms the [100] growth direction (inset).

Image of FIG. 2.
FIG. 2.

(a) XRD pattern indexed with MnO and peaks. (b) XPS of Mn and peaks of the nanowires, MnO powders, and powders.

Image of FIG. 3.
FIG. 3.

Temperature-dependent FC and ZFC magnetization measured in the magnetic field of (a) 0.1, (b) 3, (c) 8, and (d) .

Image of FIG. 4.
FIG. 4.

Hysteresis loops measured at (a) 5, (b) 8, (c) 20, (d) 30, (e) 50, and (f) . In (a)–(c), the red and green lines represent two ferromagnetic components, respectively, where their sum (solid line) fits well with the experimental data points (open circles).
