Abstract

We investigate the transport properties of ferromagnetic granular Co-Al-O films. The electrical resistivity of these films has a T² dependence at low temperatures, which can be explained in terms of scattering of electrons by spin waves. The resistivity of these films was found to have a logarithmic temperature dependence. The negative magnetoresistivity has long tails in high field ranges.
