dc.description.abstractThe first study of magnetism in the RTi2Ga4 system was reported by Ghosh et al. in 1993 [1] who observed unusual magnetic behaviour, leading them to conclude that these compounds exhibit the effects of mixed Ferro/Antiferromagnetic exchange, possibly with spin-glass behaviour. Interestingly, they observed a rather rapid increase in coercivity with decreasing temperature. In 2001, Abe et al. [2] studied a single-crystal of ErTi2Ga4 and showed that this compound is a ferromagnet oriented along the [100] direction, with quite strong magnetic anisotropy. We have carried out high-resolution neutron diffraction measurements to determine the magnetic and crystal structural parameters and magnetic ordering temperatures of the RTi2Ga4 (R=Er, Ho and Dy) compounds. These compounds crystallise in the tetragonal YbMo2Al4-type structure with the I4/mmm (#139) space group. These compounds are confirmed to be ferromagnetic. The Dy and Ho magnetic moments order within the tetragonal basal plane whereas the ordering of the Er moments is along the c-axis.en_AU
