Abstract

A neutron scattering study on a concentrated spin-glass alloy Fe₆₅(Ni_0.78Mn_0.22)₃₅ has been performed under magnetic field. The amplitude of the magnetic diffuse scattering pattern arising from short-range ferromagnetic correlations is markedly reduced by increasing magnetic field. On the other hand, the effect of external field on the diffuse scattering pattern arising from antiferromagnetic short-range correlations is small. These results show that the regions of ferromagnetic and antiferromagnetic short-range correlations (ferromagnetic and antiferromagnetic clusters) coexist separately in this random magnetic material.
