Magnetic and morphological properties of CoCu nanowires
Abstract:
Heterogeneous CoCu nanowires containing different amounts of Co (up to 50% at. wt of Co) are made by electro-deposition (ED) method. CoCu nanowires were grown in AAO templates by varying the current density. The diameter of CoCu nanowires was around 40 nm. Therefore, the growing of CoCu nanowires was compacted with the diameter of AAO templates. The XRD patterns showed that all the CoCu nanowires fabricated via electro-deposition were polycrystalline. At low current density (1.32 mA/cm2), the intensity of Cu (111) peak was very strong. Increasing the current density can be led to increase the intensity of Co (100) peak. High resolution transmission electron microscopy (HRTEM) images of the highest Co content (50%at.) wires showed the existence of layers of polycrystalline heterogeneous CoCu alternating with layers of Cu. The magnetic properties showed that the highest coercivity (7.235 kOe) and squareness (0.754) were found in the unannealed nanowires having the highest Co content.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Magnetic Susceptibility and Permeability
When diamagnetic materials are placed under an external magnetic field, the moments opposite to the field are induced. Hence, the susceptibility for diamagnets has a minimal negative value of 10-5–10-6. Since...
