Abstract
Binary alloy nanowires of Fe3Co7 system are synthesized in the highly ordered porous anodic aluminum oxide
(PAA) templates by AC frequency (5, 50, 120, and 200 Hz) conversion electrodeposition method. High resolution
field emission transmission electron microscope (HRTEM) and Lorenz TEM (LTEM) were used to study
the morphology and the magnetic domain structure of the Fe3Co7 alloy nanowires, respectively. Magnetic measurements
showed that the M-H curves presented a discontinuity in a restricted magnetic field, but with high
squareness (about 90 %). Quantitative local measurements of the magnetic properties of the nanowires are
explored by differential phase contrast (DPC) imaging. The magnetic properties, however, were significantly
affected by the AC frequency, which is correlated with the specific magnetic structure formation of Bloch line.
We reported herein a detailed investigation on Fe3Co7 alloy nanowires and their magnetic properties.
