Abstract

We investigated the magnetoresistance effect in ballistic Ni nanocontacts in the regime of conductance quantization. In magnetoresistance curves, we found that the conductance is quantized by the application of magnetic fields. The quantization is direct evidence showing the contribution of magnetostriction. The magnetostriction has the potential to control the quantum transport and giant magnetoresistance effect.
