Abstract
The physics of itinerant-electron spin-glass and the ferromagnetism in the vicinity of amorphous Fe has been clarified on the basis of the finite-temperature theory of amorphous metallic magnetism. The theory is extended to describe the noncollinear magnetism in amorphous transition metals. It is demonstrated that the transverse spin degrees of freedom yield the isotropic spin-glass and noncollinear ferromagnetism around amorphous Fe. These structures are shown to be stabilized by the higher-order biquadratic exchange energies, and are consistent with the experimental data of recent neutron scatterings and Mössbauer measurements.
