FeNi/Cu multilayer nanowire arrays were first electrochemically deposited in nanopores of alumina membranes by a single-bath pulse method, and then their magnetic behavior was investigated by using a vibrating sample magnetometer (VSM) instrument equipped with first-order reversal curve (FORC) software. The Cu deposition pulse time varied from 2.4 to 9.6 s at a constant FeNi pulse time of 2.88 s, and hysteresis curves and FORC diagrams of the resultant nanowires were extracted at magnetic field angles in the range of 0° <0< 90°. At each 9< 90°, the results of VSM hysteresis curves showed that coercivity and remanence ratio decreased with increasing the pulse time. Furthermore, magnetostatic interaction field distributions were enhanced at each 0 when decreasing the pulse time. This enhancement was ascribed to the lower separation of the ferromagnetic FeNi layers along the nanowire length, influencing the magnetostatic interactions. The vanation of FORC coercivity as a function of 0 revealed the dominance of the vortex domain wall mode in the magnetic behavior, regardless of the Cu pulse time.Abstract. © 2023 American Institute of Physics Inc..
