Magnetic study of some nanoferrite materials

The Mössbauer spectra of nanoferrite materials such as Ni0.25Mn0.75Fe2O4, Co0.5Mn0.5Fe2O4 and Ni0.4Co0.6Fe2O4 have been reported and the above materials were prepared by sol-gel combustion method using metal nitrates as source material and Polyvinyl alcohol(PVA) as...

Analyzing Nanoscale Magnetic Materials

As the advance of technology, the manufacturing process of materials has moved forward from the scale of micrometer to sub-micrometer and nanometer. Combining nanotechnology and traditional magnetic materials, nanoscale magnetic materials can be created for applications in biomedical examination and therapy as well as data recording to increase the storage space of a computer. The topic of usin...

A Reptation Model for Magnetic Materials

Reptation, or accommodation, is manifested in ferromagnetic materials in a variety of operating regimes and hence must be incorporated in models used for comprehensive material characterization or model-based control design. Because the microscopic mechanisms which cause reptation are complex, we characterize the effect in a phenomenological macroscopic manner within the context of a homogenize...
