The structural properties and magnetic behavior of CoCr nanowires with different concentration of Cr

Investigating the magnetic properties and reversal mechanisms through the incorporation of impurities in magnetic nanowires holds significant promise for future spintronic applications. CoCr nanowire arrays were synthesized using a pulsed electrodeposition technique within anodic aluminum oxide membranes, varying the chromium concentration. X-ray diffraction (XRD) analysis revealed that as the chromium concentration increases, there is a corresponding reduction in coercivity, attributed to a shift in peak orientation from hcp-Co (۱۰۱) to hcp-Co (۱۰۰). This trend is further supported by the hysteresis loop, which also indicated a decline in magnetic parameters. The magnetization reversal was observed at different chromium concentrations in nanowires with a diameter of ۳۰ nm, exhibiting a combination of vortex and transverse domain configurations.
