Microanalysis of Atomic Clustering in Electromagnetic Materials
Abstract
Possible clustering mechanism have been studies in two systems (i) intermetallic spin glass compound Co (x) Ga (1-x) and (ii) amorphous magnetic ribbons of general composition (fe,Co) (1-x) (B,Si)(x). In the CoGa system evidence for vacancy clustering has been found following bombardment by Ar(+) ions, this gives rise to dislocation dipoles up to 0.5 microns in length. Annealing or magnetic annealing of the amorphous ribbons may produce ordering of interstitial boron, phosphorus or silicon atoms or clustering of separate amorphous phases: in either casw uniaxial anisotropy is liked to be induced. Ion, proton and electron irradiation of amorphous materials can produce similary effects. Annealing above the crystallization temperature results in precipitation of second crystalline phases. (JHD)
