Summary form only given. We describe a new route of preparation of NiFe/sub 2/O/sub 4/ thin films, utilizing a sol-gel process which uses coconut water as the solvent for metal salts. This new route has obtained good results in the preparation of CoFe/sub 2/O/sub 4/ thin films by Duque et al. (2000; 2001). Stoichiometric quantities of Fe(NO/sub 3/)/sub 3/.9H/sub 2/O and Ni(NO/sub 3/)/sub 2/.6H/sub 2/O were dissolved in filtered coconut water and a sol was obtained. The crystalline phases were identified by X-ray powder diffraction measurements. The magnetic properties were determined at room temperature by applying magnetic fields up to 4 kOe perpendicular to the surface of the samples by means of a SQUID magnetometer.
