Temperature-Dependent Magnetic Properties of Electrodeposited CoPtP Alloy Nanowires

CoPtP alloy nanowires, ~ 200 nm in diameter, have been prepared by the electrodeposition method into the pores of a porous anodic aluminum oxide template. X-ray diffraction pattern shows that the wires consist of a mixture of fcc and hcp phases with CoPt (002) and CoPt (221) texture. The coercivity...

Description
Summary:CoPtP alloy nanowires, ~ 200 nm in diameter, have been prepared by the electrodeposition method into the pores of a porous anodic aluminum oxide template. X-ray diffraction pattern shows that the wires consist of a mixture of fcc and hcp phases with CoPt (002) and CoPt (221) texture. The coercivity was found to be 1150 Oe at 50 K and 760 Oe at 300 K, when the field was applied parallel to the wire axis. The temperature dependence of coercivity was explained by considering the magnetocrystalline anisotropy and thermal activation effect.
