Abstract
The results of Fe-57 Mossbauer investigations carried out on the hydro genated compounds of Dy0.73Tb0.27Fe1.5Co0.5 are presented. A change in the temperature range of the [100]-[111] spin reorientation transitio n from 200-290 K in Dy0.73Tb0.27Fe1.5Co0.5 to 100-150 K in Dy0.73Tb0.2 7Fe1.5Co0.5H0.5 is attributed to changes in the crystalline electric f ield (CEF) effects resulting from the increase in rhombohedral distort ions due to the orientational ordering of hydrogen atoms in the lattic e. The variations in hyperfine field and isomer shift are also discuss ed. (C) 1997 Elsevier Science Ltd.
