Abstract
Neutron scattering with polarization analysis has been used to examine the spin-dependent absolute neutron cross-section of and metallic glasses. is shown to be a canted ferromagnet with an average canting angle of approximately in a field of 2 T. Contrary to expectations, there is little or no canting in the samples containing ruthenium as proved by the absence of spin-flip scattering. The magnetic structure of has been studied as a function of temperature and magnetic field history. When cooled to 4.2 K in zero field the observed scattering is not consistent with the presence of a spin-glass phase. An increase in the projection of the moments in the direction of the applied field was observed when the sample was cooled to 4.2 K in an applied field of 2 T. The results are discussed in the context of current structural models of glasses.
