Magnetic properties of thin films

An alternative surface template method is reported for the preparation of colloidal superparamagnetic composites (see TEM micrographs) that could be useful for biomedical applications. The magnetic behavior of colloidal superparamagnetic composites prepared by the surface template method is compared with that of colloidal superparamagnetic composites prepared by aerosol pyrolysis. The author is able to find evidences of an interacting superparamagnetic regime at low packing fractions in the composites prepared by the template method.
