中文摘要	the hole-mediated curie temperature in mn-doped wurtzite zno nanowires is investigated using the k center dot p method and mean field model. the curie temperature t-c as a function of the hole density has many peaks for small mn concentration (x(eff)) due to the density of states of one-dimensional quantum wires. the peaks of t-c are merged by the carriers' thermal distribution when x(eff) is large. high curie temperature t-c > 400 k is found in (zn,mn)o nanowires. a transverse electric field changes the curie temperature a lot. (zn,mn)o nanowires can be tuned from ferromagnetic to paramagnetic by a transverse electric field at room temperature. (c) 2007 american institute of physics.
