Magnetic alloys in nanoscale biomaterials

The magnetic response vs applied magnetic field H from specimens across the wafer before and after VACNF growth was measured at room temperature using a Quantum Design MPMS 7-T Superconducting Quantum Interference Device (SQUID) magnetometer. The STEM images and elemental analysis of the EDX spectra...

Description
Summary:The magnetic response vs applied magnetic field H from specimens across the wafer before and after VACNF growth was measured at room temperature using a Quantum Design MPMS 7-T Superconducting Quantum Interference Device (SQUID) magnetometer. The STEM images and elemental analysis of the EDX spectra from the tips of the carbon nanofibers at points labeled I in both figures result in alloy compositions 12.07 wt pct Fe, 87.93 wt pct Co in Figure 5 and 8.15 wt pct Fe and 91.85 wt pct Co. respectively, in Figure 6.
