%X Fex(ZnSe)1-x granular films were fabricated by the radio frequency sputtering, and the structures and magnetic properties of nanometer ferromagnetic metal-semiconductor matrix Fex(ZnSe)1-x granular films have been studied. According to the dependence of low field susceptibility on temperature and the hysteresis loops at different temperature, it was found that the nanometer-sized Fe particles in granular films showed the magnetic relaxation effect at definite temperature. The magnetic property of granular films changes from super-paramagnetic into ferromagnetic at the blocking temperature TB=50K. Above the blocking temperature, the MS(T) of the granular films follows the Bloch's the spin wave T3/2 law. The causes of increase of the spin wave constant are explored and analyzed.
