Abstract
Low temperature resistivity and the transverse Hall effect (THE) are studied for sputtered amorphous GdCo films within the temperature range 4.2–400 K. These GdCo films have unixial anisotropy perpendicular to the film and in-plane anisotropy and mixed anisotropy respectively. Results show that the resistivity of all samples has a negative temperature coefficient, with a minimum in the range 300–400 K. The THE depends on sample's magnetic properties. We discuss the above measurements and suggest that the electronic transport properties in the absence of an applied magnetic field are affected by the spins of the magnetic atoms, but the general scattering mechanism of a disordered system plays a dominant role.
