摘要：

We present the electrical and magnetic characterizations of electrochemical films of polypyrrole including gamma-Fe2O3 grains of a few nanometers in size. The magnetization of one of this composite material (PPy-FF/Cit) has been measured at several temperatures as a function of the external magnetic field H. The theoretical treatment of the data shows that the grains in the polymer behave as independent monodomains and are fairly dispersed. The particle size distributions are nearly the same In the polymer and in the ferrofluid solution used for the electrochemical inclusion. These results are also consistent with TEM experiments.
