Abstract

Magnetoresistance measurements were carried out on amorphous Ni76Mn24 film in the temperature range 1.5-250 K up to magnetic fields of 120 kG. A giant resistivity noise has been observed even in higher magnetic fields, especially at about T = 70 K. Some possible mechanisms are discussed to account for the observed resistivity fluctuations.
