The authors present experiments and discuss recent results on ballistic magnetotesistance in nanometer size (on the order of 1 to 10 nm) nanocontacts grown by electrodeposition in thin wires and in thin films of a few nanometer thickness. Very large values of magnetoresistance are shown (up to 4000% and more could be obtained). These experiments as well as others are explained in terms of a dead magnetic layer appearing at the nanocontact. The experiments are also discussed in the context of magnetostriction effects, in the light of existing first principle calculations and observed inverse magnetoresistive effects.
