Distributed-feedback dye laser emitting pulses at a high repetition rate

Abstract

The electron momentum density in four amorphous alloys of composition Co70-xNixFe5Si15B10 (x = 0, 10,40 and 55) has been studied in Compton scattering experiments using 412 keV y-radiation. The results indicate that the replacement of cobalt by nickel in these alloys is associated with a transfer of charge density from the 4s to the 3d band, which is consistent with their magnetic behaviour.
