We studied resistivity, magnetoresistivity and magnetization in granular Fe-SiO 2 films. In the hopping region, magnetoresistance was found to be as large as -5%, and is isotropic for different measurement geometry, which is the signature of giant magnetoresistance due to a spin-dependent conduction
## Abstract A series of FeCoโAl~2~O~3~ granular films were prepared by a magnetronโcontrolled sputtering system. The tunneling giant magnetoresistance and nanoparticle morphology of FeCo particles in FeCoโAl~2~O~3~ granular films were directly determined utilizing a conventional fourโprobe method a
