Abstract
We investigated the magnetotransport in high quality ferromagnetic films and wires. At low temperature the conductivity decreases with decreasing temperature without saturation down to . Here we show that the conductivity decrease follows a dependency in two-dimensional films and a dependency in one-dimensional wires and is independent of an applied magnetic field. This behavior can be explained by the theory of electron-electron interaction.
