“…Recently, one-dimensional (1D) magnetic structures, especially magnetic nanowire arrays, have attracted much attention due to their unique potential applications in magnetic integrated nanosystems, perpendicular magnetic records, microwave absorbing and spintronic nanodevices. [1][2][3][4] Cobalt spinel ferrite CoFe 2 O 4 (CFO) is well known for its high coercivity, giant magnetostriction, unique light-induced coercivity change, and remarkable chemical stability. CFO has various applications, such as humidity sensors, photodetectors, biomedical, magnetoelectric devices.…”
