Abstract

The effects of Y and Lu substitutions on the structural properties of Tb2Fe2Si2C have been investigated by low temperature X-ray diffraction measurements. We find that the magnetoelastic transition observed in the undoped sample is shifted towards low temperature and the strength of the spontaneous magnetostriction is weakened with the increasing Y content. Substitution of Tb with 50 % of Y in Tb1.0Y1.0Fe2Si2C is almost sufficient to fully suppress the spontaneous magnetostriction observed in the undoped sample. Although substituting Tb with 5 % of Lu has the same compression effects to that of Tb with 25 % of Y, we observed no pronounced changes to the anomalies in the lattices parameters of Tb1.9Lu0.1Fe2Si2C (5 % Lu) which suggests that the suppression of the anomalies in Tb1.5Y0.5Fe2Si2C (25 % Y) is most likely due to the weakening of the long range magnetic correlations between Tb3+ ions upon dilution by a relatively high content of non-magnetic Y and is not the results of a chemical stress on the unit cell of the parent Tb2Fe2Si2C.
