Abstract :
Magneto-transport prosperities of the Gd film and wire have been investigated. Negative magnetoresistances due to the reduction of the spin entropy were observed at various temperatures. The magnetoresistance changes were found to depend on the direction of the in-plane magnetic field at low temperature because of the Lorenz magnetoresistance effect. The strong spin current absorption effect into the Gd was also found.
