M. Ghidini et al., Evidence for a high T-c magnetic amorphous polymorph obtained by swift heavy ion irradiation, NUCL INST B, 146(1-4), 1998, pp. 260-264
The intermetallic compound CeCo3 has been irradiated at GANIL by 1 GeV Pb-2
08 ion beams. The irradiated samples are found to be strongly amorphised. A
track diameter of 8 nm is found. The magnetic properties of the irradiatio
n induced CeCo3 amorphous phase have been studied in detail and found subst
antially different with respect to those of amorphous CeCo3 obtained by con
ventional methods. In particular, an increase of about 200 K in the Curie t
emperature is observed, suggesting that a different type of chemical short
range order might have been stabilized by irradiation. (C) 1998 Elsevier Sc
