Abstract
We have studied structural and magnetic properties of a ternary intermetallic compound Hf1-xTaxFe2 in the amorphization process using a high-energy ball mill. The X-ray diffracted intensity decreased, whereas the spontaneous magnetization at 0 K increased with the milling time. In Arrott plot analyses, the samples after milling were ferromagnetic. It is suggested that a sample subjected to a ball mill is in the amorphization process and a little disorder generated by the ball milling significantly affects the magnetic properties in this ternary compound system.
