FIG. 1.

XRD spectrum for Co–Cu alloy fabricated by electrodeposition. The lattice parameter of the Co–Cu alloy is from the XRD spectrum.

FIG. 2.

Transmission electron micrographs through low-power field (a) and high-power (b), and SAED pattern (c) of Co–Cu alloy. No clusters are found. From the SAED pattern, the lattice parameter is and the phase is fcc.

FIG. 3.

Magnetization hysteresis loop measured at room temperature using vibrating sample magnetometer for Co–Cu alloy. The saturation magnetization of the Co–Cu alloy is .

FIG. 4.

PDOS of in fcc Co, where solid line indicates PDOS for lattice parameter of and dashed line indicates PDOS for the lattice parameter of . The upper and lower half parts of each PDOS show the up and down spin states, respectively. The lattice parameter of is that of fcc Co and the lattice parameter of is that of the Co–Cu alloy. The lattice expansion narrows the bandwidth, resulting in the enhanced magnetic moment of the Co–Cu alloy.
