Magnetic moments and electronic structure of Co-base metallic glasses

Magnetization of Co 80- x T x B 20 glasses (0 ≤ × ≤ 12 at%, T = Fe, Mn, Cr, V) has been measured from 4.2 K to approximately 700 K. The data are well described in terms of the virtual bound states introduced above the center of the d band of the matrix by the light T solutes. Details of the electronic structure, some aspects of which would not be revealed by photoemission, are thereby inferred.
