A Mössbauer effect study of barium ferrite ball-milled in air

Jayasuriya, K.D.; Kaczmarek, W.A.; Wu, E.; Campbell, S.J. (Hyperfine Interactions, 1994)

The effects of dry-milling BaFe12O19 in air for periods of 190, 360, 590, 690 and 1000 h have been investigated by X-ray diffraction and M�ssbauer effect measurements. The sizes of the BaFe12O19 particles decrease on ...
A Mössbauer study of ball-milled Co?Fe?Si?B: I: dry milling

Jayasuriya, K.D.; Campbell, S.J.; Calka, A.; Jing, J. (Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1993)

X-ray diffraction and M�ssbauer effect measurements of ball-milled Co?Fe?Si?B material which had first been re-crystallized from amorphous melt-spun ribbon are presented. Fully amorphous powders have been obtained after ...
A Mössbauer study of ball-milled Co?Fe?Si?B: II: with surfactants

Jayasuriya, K.D.; Campbell, S.J.; Calka, A.; Jing, J. (Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1993)

The use of a range of organic surface active substances in the ball milling of Co?Fe?Si?B has been studied by X-ray diffraction and M�ssbauer effect measurements. Effects characteristic of superparamagnetic relaxation of ...
