摘要	The Co(Cr) and Cr(Co) solid-solution nanocapsules have been fabricated by arc discharge in atmosphere of argon and hydrogen. The structure and composition of the nanocapsules of two types are investigated by means of x-ray diffraction, high-resolution transmission electron microscope, and energy dispersive spectroscopy analysis. The Cr(Co) and Co(Cr) nanocapsules show shell/core structure with different shape characteristics. The magnetic properties of the Co(Cr) and Cr(Co) nanocapsules are studied. The blocking temperatures of the Co(Cr) and Cr(Co) nanocapsules are determined to be 96 and 14 K, respectively. The magnetization of Cr(Co) nanocapsules is contributed by the uncompensated moments in bcc chromium lattice and small cobalt particles. (c) 2005 American Institute of Physics.
