Abstract
The structural and magnetic property changes of GdMg, induced by high-energy ball milling of the ordered compound, crystallising in the B2 structure, are studied by means of X-ray diffraction and various magnetic measurements. Pairs of anti-site defects are formed, giving rise to an increasing lattice parameter and a Curie temperature that decreases from a value of 120.4 K, in the as-prepared ordered compound, to a value of 86.6 K after 20 h of milling. The relation between the number of anti-site defects and the Curie temperature appears to be linear. After 20 h of milling, the obtained material shows spin glass-like behaviour, apparently due to a change of the ratio between ferromagnetic and antiferromagnetic interactions in favour of the antiferromagnetic interactions.
