Abstract

We investigated the effect of magnetic field on Coulomb oscillation for the (Ni0.36Nb0.24Zr0.40)90 H 10 glassy alloy. The electric current-induced voltage oscillation at 1.2 and 4.0 MHz was observed from 6 to 9 T at 100 and 200 K, respectively, and the amplitude of oscillation increased with increasing magnetic field up to 15 T, accompanied by advancement of delay in phase. This is the magnetic field-induced Coulomb oscillation, derived from spin polarization of Ni atoms in Ni5Zr5Nb3 clusters.
