IntroductionThe structural and magnetic characterization of plasma arc evaporated Fe nanoparticles with different specific surface areas have been investigated by measurements of AFM, MFM, TEM, SEM, VSM. Particle sizes and shapes were observed by AFM, SEM and TEM measurements. Magnetic properties were found by MFM measurements and field dependent magnetization measurements with VSM.

Particle size characterization are performed by TEM, SEM and AFM measurements. To eliminate agglomeration, we prepared the samples by using ODCB (orthodichlorobenzene) for AFM and MFM measurements. ODCB preparation helped us to see better nanoparticles for AFM and MFM measurements. From magnetic field dependent magnetization measurement, we found Hc, Ms values. The Ms values of these nanoparticles increased with decreasing average particle size at room temperature. However, we observed the single domain structure for all nanoparticles from MFM measurements.
